Even if your flowering cannabis plant is looking rough with yellowing leaves and nutrient deficiencies, there may still be time to save your marijuana harvest.

Escape the Mid-Flower Curse and harvest better weed.

Today’s cannabis grower experienced this common problem I like to call the Mid-Flower Curse. It affects almost every grower at least once. This is when plant leaves suddenly start looking sick about halfway into the flowering stage.

Note: Some strains like Purple Haze, Green Crack, and Do-Si-Dos are more resistant to problems, but the mid-flower curse can strike any cannabis plant.

If you see nutrient deficiencies after buds start forming, don’t harvest early…

• Check out this page on how to stop flowering stage deficiencies.
• See pictures of nutrient problems caused by pH (may be the most common cause of the Mid-Flower Curse).
• Or use our free cannabis plant doctor to figure out the problem.

See how one grower beat the mid-flower curse and got a great harvest.

Our student initiated the flowering stage and his plants were growing buds a few weeks later. Despite some water stress, the plants were green without spots or nutrient deficiencies.

He watched the buds get bigger each day. Everything was going smoothly. Then, about halfway through the flowering stage, he noticed a handful of green leaves turning yellow.

Yellow tips, a few pale leaves, and the occasional brown scorched spot. 

At first, the symptoms seemed small. So he ignored them.

But it started spreading.

6 days later, those plants had a yellowish cast, especially on the hardest working leaves attached to the biggest buds.

When he looked closely at those leaves, he saw lots of brown and yellow scorch marks.

“Does it need a special supplement or nutrient?” he asked Sirius, who answered, “No, it looks like the pH is off. Check that.”

The grower thought, “How big a deal could that really be?” and told himself he’d do it later.

Another 7 days passed, and the yellowing was hard to ignore now.

Brown spots were everywhere. Even worse, it seemed like the buds had stopped getting bigger. Maybe it’s time to harvest now, our grower thought.

“Should I just harvest them now?” he asks Sirius, who replied, “Look at all the white hairs on the buds, they’re not ready yet. Make sure to check the pH of the runoff too. Try to keep the leaves healthy until harvest.”

The grower finally checked the pH of his runoff water, expecting around 6-7 (the pH zone that helps prevent nutrient problems in soil). After all, he was always giving them water pH’ed exactly to 6.5.

Yet he was shocked to discover his runoff water measured at 5.4 pH. Way too low.

It really was the pH causing these leaf symptoms the whole time.

Once he fixed it, the discoloration stopped spreading. And although most yellow leaves never turned green again, the buds immediately started growing bigger.

By harvest day, the buds had doubled in size.

He dried the buds in the grow tent.

After being dried and cured, the resulting buds were dense and beautiful. He beat the curse.

Lesson: How to Defeat the Mid-Flower Curse

Growers experience the mid-flower curse because most cannabis plants stop making new leaves about halfway through the flowering stage.

From then on, plants put their energy towards developing buds instead of maintaining foliage. Leaves stay green and healthy in ideal conditions even if they’re working hard. That means it’s up to you as the grower to give great care so your cannabis plants keep enough healthy leaves to last until harvest.

Happy leaves help cannabis plants produce great bud quality.

Better late than never is often true for ailing cannabis plants, especially in the middle of the budding phase. Even though you see some yellow leaves now, you might think, “Oh well, it’s already a lost cause” but the truth is every day of good care helps plants develop bigger, denser, and more beautiful buds.

Even after some leaves are lost, it is worth saving the remaining ones. Partly green leaves still help. Don’t give up on your plant just because it’s starting to look a little rough.

Leaves turn light into energy. No leaves = no energy to grow.

What do you do if leaves turn purple? Even purple leaves should look healthy without brown spots or scorch marks on the leaves or edges, like this Runtz plant with green leaves that slowly turned purple close to harvest.

Your #1 job: don’t ignore problems. If you notice yellowing leaves or spots, try to identify the cause and fix it as soon as possible instead of waiting until symptoms spread.

• Learn how to stop flowering stage deficiencies.
• See pictures of nutrient problems caused by pH (common cause of the Mid-Flower Curse).
• Use our free cannabis plant doctor tool if you still need help.

Keep your cannabis plants as healthy as possible, even after problems start forming. Too many growers give up on their plants right when they need extra care the most.

In our harvest book, we help you finish strong and harvest buds at the right time to maximize density and effects.

Main Takeaway: Aim to keep lots of healthy green (or purple) leaves to power bud growth, so your plants produce maximum yields and density.

You now have the power to prevent the mid-flower curse from attacking your harvest. Your jars will thank you.

Got marijuana plants growing in soil? Most nutrients work, but cannabis plants grow best when your nutrients are designed to grow weed plants in soil.

3 Top Soil Nutrients for Growing Weed

• Fox Farms Nutrient Trio for Soil – professional marijuana soil nutrients, mostly organic ingredients.
• Botanicare PureBlend (Grow & Bloom) – pro nutrients for beginners, one bottle per stage.
• Dyna-Gro Grow & Bloom – cheap & effective, use in soil at 1 tsp/gallon.

The Fox Farm soil nutrients are the most popular nutrients for growing cannabis in soil.

Sirius grew these in good cannabis soil with Fox Farm nutrients and LED grow lights.

Quick Guide: When to Give More Nutrients in Soil

These are signs your cannabis plant in soil needs more nutrients overall. Giving soil nutrients to plants with the following symptoms typically solves the problem within just a few waterings. Other nutrient deficiencies are often actually a pH problem.

Pale, lime green cannabis plants in soil = you need to add more nutrients.

If many lower leaves turn yellow and fall off, especially while buds are forming, it’s a sign the plant is “stealing” nutrients from the bottom of the plant to give to the hard-working leaves at the top.

That means if many lower leaves are turning yellow and falling off on their own, you need to add more nutrients.

Add more nutrients if bottom leaves are turning yellow and falling off.

If the bottom of your pot looks like this, the cannabis plant needs more nutrients.

When the Nutrient Problem is Caused by PH

If you see these different symptoms, the cause is likely a pH problem, not needing more nutrients. See pictures of deficiencies caused by pH.

If you see brown spots, or yellow leaves are “stuck” on the plant, it’s likely actually a pH problem.

Another example of a nutrient deficiency caused by incorrect pH.

You can still get a great harvest even if you have some nutrient problems. But you get the best cannabis yields and bud quality when plants get extra nutrients while buds are forming.

Great nutrients grows healthy plants – see the grow journal.

Do You Even Need Special Nutrients to Grow Marijuana in Soil?

• Cannabis has high nutrient needs, especially in the flowering/budding phase. Without enough nutrients during budding, the plant won’t make buds as big as they could be.
• You can avoid using extra nutrients altogether by growing in well-amended composted soil and transplanting your cannabis into a nice big pot with fresh composted soil right before the switch to the flowering stage, which should be enough to last through the flowering stage. In composted soil, tiny microorganisms slowly bread down the nutrients for your plants, so the nutrients are fed to the plant slowly and regularly.
• A potted cannabis plant in regular (non-composted) potting soil often uses up all the nutrients in the soil before they even make it to the flowering stage. After about 3-4 weeks of growing in an average sized pot, a cannabis grower either needs to repot the plant into new, fresh soil, or supplement with extra nutrients in order to get everything to the plant that it needs.
• There are “natural” ways to provide extra nutrients to your cannabis (for example egg shells, coffee beans, dolomite lime, etc all add minerals and nutrients) but these usually do not break down fast enough or consistently enough to make sure your cannabis doesn’t run into nutrient deficiencies. Another problem with using things like this is that giving your plant too much of one nutrient can actually make it deficient with another nutrient. So it can be difficult to get the right proportions right unless using a soil recipe that’s specialized for cannabis or by adding extra nutrients in the water.
• Want more info? Since it’s just a weed, why can’t I grow cannabis in the regular dirt outside?

Fox Farms Ocean Forest soil (pictured here) is a top soil for growing cannabis. It just works.

How to Get Enough Nutrients to Your Marijuana Plants

To make sure your cannabis plants don’t run into nutrient deficiencies while growing in soil, you need to either…

• Grow with composted soil OR
• Regularly transplant to new. fresh soil OR
• Grow in a really, really big pot with tons of soil OR
• Supplement with specialized marijuana nutrients formulated specifically for growing cannabis in soil (recommended)

Conclusion: Adding soil nutrients to the water tends to get the best cannabis yields, potency, and density.

What Soil Should I Get to Grow Weed?

What Are the Best Soil Nutrients?

But are they the best marijuana nutrients? Which one is the best?

There are so many nutrient options out there! How can growers figure out which ones are actually the best cannabis nutrients? In fact, what makes a nutrient system good or bad for growing cannabis in the first place? The answer is it’s about the NPK nutrient ratios!

* In a pinch, nutrients for cactus or succulents can be used in the flowering stage until you get better nutrients because they have similar nutrient ratios

These aren’t the only nutrient ratios that will work for growing cannabis, but these ones work well. Adding cannabis nutrients to your grow can help you get the best potency, yields and growth from your plants, especially in the flowering stage when cannabis uses a lot of nutrients to make bud. Cannabis plants have two stages of life and they need the right nutrients at the right time.

Note: Don’t use anything with time-released nutrients (like fertilizer spikes, or Miracle-Gro soil – they deliver too much N in the flowering stage).

Most nutrient bottles have 3 numbers, often called N-P-K, which stands for Nitrogen, Phosphorus and Potassium

(Why “K? The atomic symbol of Potassium is “K” from Neo-Latin kalium)

Marijuana plants need different ratios of these 3 nutrients (as well as several micronutrients) depending on what stage of life they are currently in.

For example, cannabis plants in the vegetative stage need nitrogen to power the growth of leaves. In the flowering/budding stage, cannabis needs less nitrogen and greater levels of phosphorus to assist with proper bud growth.

Because of the varied nutrient needs of the cannabis plant, it’s often easier for many growers to use a professional nutrient system made for a plant like cannabis, instead of trying to mix up their own. With a professional nutrient system, you don’t have to figure out your own changing nutrient ratios, and you don’t have to worry about chemical reactions that occur from combining different types of nutrients incorrectly (which can create fertilizer salts and cause nutrient lock-out).

A professional cannabis nutrient system will save many growers a lot of time, frustration and money. There are many nutrient systems to choose from which have been created by long-time cannabis growers and breeders around the world!

When it comes to finding a nutrient system to use with your cannabis plants, the first question you ask yourself should be: “What is my growing medium?”

Warning: When it comes to growing cannabis, avoid any nutrients which claim to be “extended” or “slow release”! They can cause all types of unexpected problems.

If you’re growing in soil, you will want to get nutrients made for soil.

With all nutrient systems, don’t start at full strength or it might burn your cannabis plants!

Different strains have different preferences, and some plants are very sensitive to nutrient burn.

How Much Soil Nutrients to Give Cannabis?

• Start at half strength – I recommend starting new nutrient systems at half-strength and only raise the nutrient levels as needed.
• Fast-growing plants need more nutrients – If your cannabis plants are growing very fast (inches a day) they likely need full-strength nutrients regardless of the type of grow light.

Other Factors That Affect Nutrient Levels

• Small grow lights require less nutrients for plants to be healthy, on average – Many home growers will never need to raise nutrient levels above half-strength because their plants are under relatively small LED grow lights (100-200W). Plants just aren’t “digesting” enough light to need lots of nutrients.
• Big grow lights often require need full-strength nutrients – On the other hand, cannabis plants are under powerful, bright lights may require full-strength nutrients (or even more in rare cases).
• Individual plants have different needs – Some strains or specific cannabis require more or less nutrients. You sometimes notice you have plants in the same environment, but some plants get “hungry” for nutrients while other plants getting the same conditions are getting enough or even too much.
• Pay attention to plants more than anything! If a plant looks like it needs more nutrients, give it more. If it looks like it needs less, give it less.

Plants turn yellow or lime green all over when they need more nutrients overall.

If leaves are dark green all over, they probably need less nutrients overall.

“Nutrient burn” (dry, brown, possibly curling tips) is another sign of too-high levels of nutrients or supplements. Pay extra close attention if nutrient burn affects all the leaves at once, especially if you see it happen right after raising nutrient levels or adding a new supplement.

Nutrient burn on all the leaves is another signal the nutrient levels are too high.

Plants use light for food (and to power the growth of buds), not nutrients. Just like eating a bunch of multi-vitamins every day will make you sick, giving plants too high levels of nutrients can make them sick, too. With plants, just like humans, you will get the best results by paying attention to nutrient needs on a regular basis. Don’t wait until your whole plant is yellowing to try to figure out the problem!

Some growers try to push their plants to the limit of what they can take, giving stronger and stronger levels of nutrients until plants show signs of nutrient burn, but I don’t believe this is necessary. Sometimes less is more. I believe that as long as your plant is not showing signs of deficiencies (such as growing pale green leaves towards the bottom of the plant), you are generally in the right range.

Many cannabis growers will find that professional nutrients work well at half-strength, and only growers with very bright lights and fast-growing plants will need to raise nutrient levels above that. There are also certain strains that seem to do better at higher nutrient levels than most others.

Here are pictures of cannabis plants with nutrient problems (and solutions).

Please, save yourself the time and frustration – get a nutrient system that’s proven to work for growing cannabis! If cost is a worry…

​An Example of Cheap (But Effective) Cannabis Nutrients: Dyna-Gro Grow & Bloom. Use Dyna-Gro “Grow” bottle in the vegetative stage & Dyna-Gro Bloom bottle in the flowering stage. This cannabis nutrients work great for growing marijuana. You don’t need anything else besides these two bottles of nutrients to grow weed all the way to harvest and this simple cannabis nutrient system is cheap (effective for soil, coco coir and hydro!). If you’re not sure which nutrients to get and you’re on a budget, consider going with Dyna-Gro!

An easy and simple nutrient systems that for beginning cannabis growers in soil is the Fox Farms Nutrient Trio for Soil. These are professional-level nutrients, and one of the the most popular nutrient systems for growing weed in soil.

Fox Farm Nutrient Trio – excellent, mostly organic cannabis nutrients.

The Fox Farms trio works great for growing any cannabis strain, without needing any additional supplements.

Tips for Growing Cannabis in Soil

• Low Levels of Nutrients Given Regularly is Much Better Than Giving a Lot of Nutrients at Once!

The most common mistake made by beginners growing cannabis in soil is they water their plants too often. Overwatering is almost never a case of giving your plants too much water at once. Instead, overwatering cannabis in soil is almost always caused by giving the plant water too often.

Learn how to water seedlings in soil (day-by-day watering schedule).

Never overwater your seedlings again, just use this seedling watering schedule.

How to water adult cannabis plants in soil

1. Wait until the top of your soil feels dry up to your first knuckle (about an inch deep)

2. Add nutrients to your water (if needed), then adjust the pH. Most soil growers only add nutrients every other watering, or even less often, but you will always need to adjust the pH of your water.

3. Start watering your plants and continue to add water until you see at least 20% extra runoff water drain out the bottom of your pot. Go back to step 1.

Use the above directions to water older plants in soil, like these 30-day old plants

Hey cannabis growers! We all know how annoying nutrient problems can be. And obviously, the best thing to do for your cannabis plant to prevent growing problems is give them the conditions they need to thrive. But did you know some strains are naturally more resilient than others? Certain genetics are less likely to experience problems. Yes, some special strains can experience sub-optimal conditions and still thrive.

Some cannabis strains make amazing buds even if you make some mistakes.

But which ones? These strains typically share some features…

• Fast-Flowering Strains – Perhaps it’s because they just don’t get enough time to get sick, but fast-flowering plants are often ready to harvest before you start running into significant problems even in sub-optimal conditions.
• Buds Grow as Nuggets, Not “Colas” – “Cola” is Spanish for tail, some growers use the word cola do describe a long fat bud. Sometimes these types of buds are called “baseball bats” (or in less polite company, “donkey d**ks”). These strains are high-yielding, but also prone to bud rot because they focus energy on producing long, fat colas. And for the purposes of today’s subject, tend to take out literally everything they can from the plant to their own detriment. These strains happily kill themselves to make buds. Which is kind of cool in its own way, but if you’re just looking to get a solid harvest with high bud quality, you’ll find the strains that tend to grow buds as small nuggets tend to thrive and stay healthy while their cola-wielding friends are sucking out every last nutrient as the plant slowly dies around the buds.
• Stable, Established Strains – Strains that are well-bred to be predictable tend to be more resistant to problems than raw crosses or experimental strains. That’s because breeders often refine their best strains for years to ensure that every batch of seeds grows exactly the same – fast and healthy!
• Legendary Strains – Some strains become legendary for a reason. Often, it’s because they just have something special to offer. Strains like Blue Dream, Girl Scout Cookies, Bruce Banner, and others were developed over years by home growers and commercial growers together. They’ve stuck around because they are all around great strains, and that’s also why you see they are some prominent in the history of so many new strains. Although not all versions of these legendary strains are great, I’ve found when you get them from a good breeder, they’re more likely to perform above-average than when you’re growing a strain you’ve never heard the name of. I love a strain name like “Candy Pegasus” as much as the next person, but you need to be more wary of brand new strains.
• Direct-to-Grower Breeders – Strains from breeders that sell directly to customers are often a great choice. I think it’s because they’re also the ones answering questions when growers run into plant problems. The further removed the breeder is from the grower, the less they may be thinking about how plants grow, since breeders are usually growing in ideal conditions. These growers breed only for what the buds are like, and may not “stress test” their plants, unlike breeders who also consider growth patterns. Direct-to-growers breeders pay extra attention to ensure their strains tends to germinate quickly, efficiently use nutrients, grow fast, and never herm. For example, I have found the homegrown strains from Seed Supreme, Seedsman, and MSNL tend to be easy to germinate, fast-growing, and overall resistant to problems.

Looking for some specific recommendations? Let’s explore some hardy cannabis strains that can handle a challenge!

Blue Dream by DNA Genetics

Why It’s Resilient

• Fast-Flowering – Ready to harvest with a 8-10 week flowering stage.
• Stable, Established Strain – This version has been stabilized from the original clone-only strain over several years.

Why It’s Resilient

• Fast-Flowering – Ready to harvest with a 8-10 week flowering stage. These buds won’t “go long” on you.
• Stable, Established Strain – This version has been stabilized from the original clone-only strain over several years.
• Legendary Strain – Anyone who’s been watching cannabis cups or visits dispensaries has probably seen this strain many times. There are sooooo many “Cookies” strains that have been developed from this strain as well. It’s legendary for a reason, and this refined version may have even better bud effects and sweet “cookies” smell than the original clone.

Ideal For: Those seeking a strong, euphoric effect, sweet-smelling buds, and a resilient growth profile.

Get Girl Scout Cookies – Famous for a reason!

Growing Girl Scout Cookies Tips

Easy to grow, easy to train. Can handle warmer temperatures than some other strains, which makes it a good choice if you’re struggling to control the heat in your grow room, or live in a very warm climate. Great yields even if you make some mistakes.

Honorable Mention: Platinum Cookies is a Cookies cross that has that special something. Check out my full Platinum Cookies strain review.

Purple Ghost Candy by Seedsman

Why It’s Resilient

• Buds Grow as Nuggets – Chunky, dense nugs galore. Often grows with purple tinges all over the buds as long as you provide high levels of light.
• Stable, Established Strain – This strain was a banger from the beginning, but has been refined over the last few years into a gold standard stabilized strain.
• Direct-to-grower – Seedsman runs a full seed bank full of strains from many different breeders, but I’ve consistently found their in-house strains are just all around easy to grow with great germination rates and lower chances of problems.

Ideal For: Growers looking for a potent high and a sturdy plant with big yields. Best for growers with a bigger grow space. This plant needs room to stretch (either tall or wide). Performs great as a single plant as it tends to completely fill up the grow space available.

Get Purple Ghost Candy – One of my favorite strains lately!

Growing Purple Ghost Candy Tips

I’ve found this strains tends to grow big plants with huge yields, yet grows buds as nuggets so you don’t run into the same problems as other high-yield strains. Grows lots of side branches and responds very well to pruning, bending branches, and defoliation.

One of the reasons I chose this strain over the others I’ve grown from Seedsman is the outstanding bud quality. Buds tend to grow dense, beautiful, and POTENT. Make sure to wait until buds are totally mature before harvesting for the best bud quality. Not for the faint of heart or casual smokers!

Dirty Unicorn by Dirty Bird Genetics

Why It’s Resilient

• Fast-Flowering – Typically ready to harvest in about 9 weeks from 12/12.
• Buds Grow as Nuggets – Buds are dense and sparkly, and produce tight nugs.
• Stable, Established Strain – Dirty Bird Genetics took a famous Thug Pug strain (Unicorn Poop – a non-feminized strain that is always sold out) and worked with it for over two years to make an amazingly consistent strain that gives you the wonders of the original genetics but in feminized, stabilized form.
• Direct-to-grower – Get it straight from the breeders.

Ideal For: Those who want a clear-headed, energetic high with top-of-the-line bud appearance and smell.

Get Dirty Unicorn – Unusual name, memorable buds!

Growing Unicorn Poop Tips

Plants tend to grow on the taller side, with extra space between nodes, but that actually makes it really easy to train this plant to grow into whatever shape you want. Vigorous, fast growth. The seeds germinate fast and seedlings tend to start strong.

Bruce Banner by Seed Supreme

Why It’s Resilient

• Buds Grow as Nuggets – Dense, tight nugs galore!
• Stable, Established Strain – Developed over years
• Direct-to-grower – Get it straight from the source.

Ideal For: New growers, low-maintenance gardens, and those prone to minor nutrient mishaps. Offers a powerful, uplifting high.

Get Bruce Banner – Named after the Incredible Hulk for the sheet potency of buds

Growing Bruce Banner Tips

A robust strain that can take extra nutrients and warmer temperatures. Great yields, easy to grow, and overall just a pleasure of a plant.

Choosing the right cannabis strain can make a big difference. Hardy strains are known for their ability to thrive in less-than-perfect conditions, which makes them perfect if you’re looking for a consistent harvest with minimal issues. It can help when you opt for fast-flowering strains, those that grow buds as nuggets, stable and established genetics, legendary strains, and those from direct-to-grower breeders. Remember, the best cannabis strains are the ones that give you what you want, how you want it!

Happy growing!

The post Which Strains Get Fewer Nutrient Problems or Deficiencies? appeared first on Grow Weed Easy.

This article shares what House & Gardens says about their own nutrients and supplements. It seems hard to find this information all in one place so I’ve compiled it for you. This is what I found about about these products according to company websites and Amazon product descriptions.

The House & Garden lineup is an expensive but effective line-up for growing cannabis. From a grower: “H&G was started by a top researcher from Canna. They are right outside of Amsterdam and because cannabis is legal there, so both Canna and H&G are able to do R&D using cannabis. I don’t know about Canna, but I know that House and Garden makes all their own nutrients in-house and they work great.”

This cannabis plant was grown using the House & Garden Line-up (Soil A + B as base nutrients, plus the supplements Roots Excelurator, Algen Extract, Bud XL, and shooting powder)

The biggest downside of House and Garden (besides price) is it can be hard to find online. Sometimes you can only find this brand at a hydro store, but I’ve included links where you can find them online. Get a custom nutrient schedule directly from the people at House & Garden via their free online nutrient calculator.

Options for Base Nutrients

These are the “base” nutrients for your cannabis plants. With most nutrient companies, you can grow cannabis with just the base nutrients, but House & Garden provides very low levels of nutrients in these bottles, and you need to get at least some of the supplements to ensure your cannabis plants get everything they need. I highly recommend contacting them if you’re confused or have questions.

• Soil – Soil A + B – “Two-part base nutrient for soil-based growing media”
• Coco Coir – Coco A + B – “Two-part base nutrient for coco coir-based growing media”
• Hydroponics (Recirculating) – Aqua Flakes A + B – “Two-part base nutrient designed for recirculating hydroponic systems”
• Hydroponics (Drain-to-Waste) – Hydro A + B – – “Two-part base nutrient for drain-to-waste hydroponic systems”

Optional Cannabis Supplements:

Yes, they have a lot of supplements! Do you need them all? No. No grower needs all these supplements. But if you’re looking for the most popular House & Garden supplements for cannabis growers, they are: Roots Excelurator, Algen Extract, Bud XL, and Shooting Powder. I’ve bolded those ones in the list below.

• Roots Excelurator Silver – “The best root growth promoting hydroponic nutrient on the market” (hydro version)
• Roots Excelurator Gold – “The gold standard of root growth enhancers” (soil / coco version)
• Drip Clean – “Keep your equipment, growing media, and plants free of salt buildup”

Drip Clean

Drip Clean – “Keep your equipment, growing media, and plants free of salt buildup”

Official Website Description of House & Garden Drip Clean (June 2024)

Salt buildup has a multitude of downsides. It can inhibit your plants from absorbing nutrients as well as they should, clogs up piping, and forces you to flush thoroughly before harvest — it wastes time AND money. Drip Clean was created to solve this problem. Drip Clean is used with each feeding throughout the grow cycle, keeping salt buildup at bay. This allows your plants to absorb added nutrients at their highest possible rate and cuts your flush time to only about 3-4 days. On top of that, any beneficial microbes you add to your feeding regimen will be unaffected; this is due to Drip Clean’s utilization of ionic bond associations rather than corrosive methods to keep your system clean.

PH Stabilizer

PH Osmosis / Stabilizer – “Maintain pH stability when using reverse osmosis (RO) water.”

Official Website Description of House & Garden PH Stabilizer (June 2024)

Keeping your reservoir pH balanced with RO water can be a little tricky. Due to its very low ppm, RO water is prone to dramatic fluctuations when nutrients are added, or even just from exposure to air — that’s why we formulated PH Osmosis/Stabilizer. pH Stabilizer provides the perfect blend of minerals to RO water so it stabilizes pH while not causing any unwanted chemistry. After adding it, you can implement other nutrients without worrying about drastic changes in pH. While some growers use CalMag as a “band-aid” buffer for RO water, it only keeps the pH stable for around 2 days and often includes nitrogen, which you don’t want around during the flowering stage. pH Osmosis/Stabilizer maintains pH stability for up to 10 days, with no added nitrogen and much less potential for nutrient lockout.

Disclaimer: PH Osmosis/Stabilizer works in all growing media and contains no dyes, synthetic PGRs, or detectible heavy metals. In order to maximize activity and shelf life, sealed bottles and containers should be stored between 45 to 85 degrees Fahrenheit (7 to 29 degrees Celsius) and should be used within one year of opening the seal.

Magic Green

Magic Green – “Provides vital nutrients directly to the foliage”

Official Website Description of House & Garden Magic Green (June 2024)

Magic Green is a product that works well on multiple levels. Primarily, this foliar spray supplies crucial macronutrients to the plant directly through the foliage, when nutrient absorption through the roots is just not doing enough. This can help to “green up” yellowing leaves faster, with noticeable improvement seemingly overnight. Magic Green also acts as a leaf strengthener and provides essential nutrients required throughout your plants life cycle.

Disclaimer: Magic Green works in all growing media and contains no dyes, synthetic PGRs, or detectible heavy metals. In order to maximize activity and shelf life, sealed bottles and containers should be stored between 45 to 85 degrees Fahrenheit (7 to 29 degrees Celsius) and should be used within one year of opening the seal.

Magnesium Boost

Official Website Description of House & Garden Magnesium Boost (June 2024)

Magnesium Boost – “Supplies additional magnesium for large-leafed plant varieties”

Magnesium Boost is perfect for revitalizing your plants when they’re needing a little extra magnesium. It is especially effective for longer vegetative times, and in strains with thicker leaves and certain indica-dominant hybrids. You can usually tell when your plants are deficient when the leaves start turning yellow while the veins stay green — in this scenario, a little magnesium goes a long way.

Cannabis buds are generally green, but can also be pink or purple with certain strains.

“How much will electricity cost each month?”

If you’re just growing a few marijuana plants for personal use, it will cost you $20-$100+/month for electricity, depending on what grow lights (electricity) and nutrients you use. On average, I’d say a hobby-size grower might pay about $50/month to grow, but it depends greatly on your setup and local electricity costs! How much will electricity cost each month?

“How can I increase my marijuana yields?”

We have quite a few techniques to choose from or combine! See some of our most popular pages:

Even More Ways to Increase Cannabis Yields

1. Increase Light Intensity (plus choose right light for desired yields & possibly add CO2)
2. Manipulate How Plants Grow (a free way to yield more bud indoors)
3. Provide Right Nutrients (low Nitrogen in the flowering stage, and remember sometimes less is more!)
4. Control Growing Environment (let the growing environment work for you)
5. Harvest Plants Properly (most importantly, don’t harvest early!)
6. Lastly, it’s important to remember that the strain has a major effect on yields!

Two small cannabis plants can yield several ounces of premium weed!

“How can I grow weed privately?”

Read guide on growing weed indoors without anyone knowing. But remember the most important factors to stealth growing: “No tell, no smell, no sell.” Never tell anyone, not even your best friend, that you’re growing. Be on top of preventing smells, and never ever sell cannabis. Breaking one of those 3 principles is how 99% of growers get found out!

“What if my plants get sick?”

The most common issue a grower runs into is a pH imbalance. Barring that, your marijuana plants likely either have a nutrient deficiency, heat or light stress, or are being attacked by some sort of marijuana mold, pest or bug. Whether you call it weed, cannabis, sinsemilla, skunk, pot, marijuana, or something else, the plant known as Cannabis Sativa is a hardy weed in the wild and can actually be easy to grow indoors at home when you know what to do.

Growing Medical Marijuana

“Medical marijuana” has become a household name. The body of evidence for medical marijuana in the treatment of cancer and other illnesses is growing every day. And for those who need medical marijuana, growing weed indoors is the perfect way to ensure a safe, regular supply of buds, for cheap.

In fact, when you grow weed indoors for personal use, you often end up with way too much. If you catch the growing bug like I did, and if you start enjoying the process of tending your cannabis garden just for the sake of gardening, you’re going to have to find a way to press, cook, freeze, and concentrate all your extra buds. 🙂

As you probably know, both medical marijuana and recreational cannabis have been decriminalized or legalized in many places around the world and weed is becoming legal in more places every day! Yet there still aren’t many simple indoor “how to grow weed” guides for beginners (even for those who legally grow, such as medical marijuana users and those who live in places where marijuana is legalized for personal use).

If so, I know how you feel. It can be hard to weed out all the bad information on the internet and find well-researched, free tips or instructions on how to grow your own cannabis. That’s why Grow Weed Easy.com aims to be a simple online resource that explains from start to finish what you need to do when growing cannabis so you can learn how to grow cannabis with great yields and potent buds, even if you only have a small grow space like a closet or even a computer case.

Emergency Resources for Sick Seedlings!

If you’ve got unhappy cannabis seedlings, I’ve got the solutions. Sometimes the hardest part of growing cannabis is just germinating the seeds and caring for seedlings. If you’ve never gardened or planted a seed before, you may have to learn everything from scratch. And with expensive and hard-to-get marijuana seeds, there’s a lot of pressure to get things right the first time.

This tutorial will help you with some of the most common seedling problems, so you can quickly get the fix. Make it so that your first few weeks go without a hitch.

Note: At GrowWeedEasy.com, we have resources for almost every common growing problem, so check out our cannabis plant doctor or use the search bar on the side of the website if you have a specific problem.

My Seedling Problem is…

If your seedlings are sick and you’re still investigating the problem, move your grow light up and don’t attempt to train your plants or do anything new until they’re better! If you avoid stressing them out any further, they often recover much more quickly.

Germination Problems

• Soil or Coco: Fail-Proof Germination Guide
• Hydroponics or DWC: Fail-Proof Germination Guide
• Are My Seeds Good? (How to Know if Seeds Are Viable)
• Seedling Growing Upside Down with Root Up

Germination problems? We’ve got you covered!

Yellow Leaves

• Why do seedlings turn yellow? – There are many reasons you might see a yellowing leaf on young plants, but this tutorial breaks down the most common.

This yellow seedling was overwatered. Seedlings don’t like “wet feet”. Too much water is the most common reason you’ll see yellow leaves on seedlings.

Curling or Clawing Leaves

• Clawing or curling leaves – Like yellow leaves, there are actually a few different triggers for clawing or curling, including watering practices and nutrient levels.

In this case, the clawed leaves are also from too much water. Small seedlings in big pots need careful watering until they’re drinking more.

Bad soil will sabotage you! Thick muddy soil prevents seedling roots from getting enough oxygen

Seedling is Wilting or Droopy

If you notice your plant is droopy all the time (even in the mornings right after lights turn on, when plants are at their perkiest), it usually means there’s something going on at the roots. The seedling might be getting too much or too little water at a time, possibly watering too often or infrequently, or its roots could be sick/damaged. The other major cause of drooping and wilting is high or low temperatures, and occasionally really high or low humidity.

• Overwatering vs Underwatering: How do you know?
• Root problems (coco or soil)
• Root Rot (hydro)
• Heat Stress
• Temperature Tutorial
• Humidity Tutorial

This seedling was given too much water for many days. Notice the green algae growing on top of the soil.

Underwatered seedling – When there’s not enough water at the roots, leaves are dark green, possibly clawed or droopy, and growth is slow

In hydroponics, when you see a droopy seedling it usually means there’s something bad happening at the roots

Burnt Leaf Tips

• Usually caused by nutrient burn (too much nutrients)
• Sometimes caused by a deficiency such as a copper deficiency
• Also caused by incorrect pH or overwatering/underwatering

Seedling with a single burnt leaf due to slight underwatering. You can tell it’s not nutrient burn because it’s only affecting a single leaf (nutrient burn tends to affect leaves all over the plant).

Why Are Stems Purple or Red?

• Could just be the genetics
• Can be triggered by cool temperatures or too-bright light
• Sometimes it’s a sign of stress or a deficiency
• Learn whether your red or purple stems are normal

Purple stems are normal for some strains, though they also appear on plants that are cold, stressed or experiencing a nutrient deficiency. Sometimes bright light triggers purple stems, like a tan.

This seedling appears healthy. If you don’t see any other symptoms, you probably don’t need to worry about it. But keep a close eye. If a seedling with purple stems also grows slow or has markings on the leaves, it means something is wrong. Investigate!

Why is My Seedling So Tall?

• If your seedling keeps growing taller and taller without a lot of leaves, it usually means it needs more light.

Tall, “leggy” seedlings need more light. They’re doing their best to stretch towards the nearest light source! Quick aside: Avoid germinating multiple seedlings in the same pot. It can be difficult to separate them.

Why Are Leaves Curling?

• This is often caused by heat stress or overwatering
• Sometimes too much light or very dry air can trigger it, too

These wavy leaves are the result of too much heat, and possibly slight overwatering

Another example of heat damage plus overwatering (the same triggers can be expressed in multiple ways)

​What to Focus on During Your Seedling’s First Month

• Perfect Environment – humidity, temperature, airflow, CO2/fresh air, reflective walls, etc
• Enough Light – If your seedlings are growing tall it means that they want more light! Remember, in the flowering stage your yields will be directly related to how much light your buds are getting!
• Not Too Much of Light – Too much light can hurt your plants even in cool temperatures! Seedlings are more sensitive than adult plants, so be careful not to overload them with light too quickly! If you think your seedlings may be stressed from too high levels of light, move your grow light up a few inches and see if they improve.
• Watering properly (one of the hardest parts for a lot of new growers!) – How to Water Plants Perfectly Every Time. I promise it gets easier!
• Not Too Much Love – Seedlings need some breathing room! (i.e. avoid overwatering, touching/messing with plants too much, giving too high levels of nutrients or supplements, etc.). They want you to love them and watch out for them, but they also need to get work done 🙂
• Start Thinking About Plant Sex – For several weeks after germination, a plant’s sex is hidden and has little effect on how your plants grow. However, if you are not familiar with the difference between male and female plants (only female plants make buds), now is the perfect time to read up!

The following symptoms are for when your cannabis leaves are “clawing” or curling up or curling down. Sometimes known as “The Claw”. I’ll give a short explanation with pictures of each problem, plus links to the solutions! Fix this common (but hard to diagnose) marijuana problem today!

Nitrogen Toxicity

A Nitrogen toxicity is the result of the plant getting too much Nitrogen (usually from too high levels of nutrients overall, or by using a Vegetative nutrient in the flowering stage). It causes dark green leaves and curled tips (“the claw”).

One of the main symptoms of a Nitrogen toxicity is curled tips (“the claw”)

A plant with a Nitrogen toxicity tends to be dark green all over

Wind Burn

Caused by too much wind. You’ll notice that the leaves further from the fan don’t have symptoms.

Example of too much wind on your leaves

Learn more about cannabis wind burn

Bad Soil / Overwatering / Underwatering

You can help prevent over and under-watering your cannabis plants by always starting with good soil or coco coir.

Bad Soil

Bad soil is usually thick and muddy. Plants in poor soil will droop (often with unhappy curly leaves) no matter your watering practices.

Avoid thick soil that stays wet for a long time and doesn’t drain well

Overwatering

Overwatering makes leaves fat with water, and they tend to curl down and droop

Overwatering (especially when combined with heat) can also cause leaves to curl up

This plant was grown in muddy soil, and the curling, unhealthy leaves kept getting worse and worse over time!

​

Underwatering

Underwatering causes symptoms that often look like overwatering, but you’ll know it’s underwatering if the plants perk up each time after you water them.

Root Problems

Although often caused by overwatering, once the roots are sick you’ll see symptoms for a little while even after you start watering your plants properly.

Unhealthy roots can cause all sorts of problems including curling and clawing!

Unhealthy Roots in Soil/Coco

This plant’s roots were damaged from being overwatered and too hot for several days. As a result, the leaves took on a strange, blistery appearance.

This plant suffered from heat combined with overwatering for several days. This damaged the roots and gave it this odd leaf curling.

Learn more about root problem and symptoms

Root Rot

Root rot is something marijuana hydroponic growers can suffer from if pathogens attack the roots. It is often triggered by heat and/or lack of bubbles near the roots.

Root rot can cause curling leaves and brown patches as well as sometimes other nutrient deficiencies

Rootbound

If a plant stays in the same container for too long, the roots will eventually start wrapping around the edges of the pot. This is known as being “rootbound” and causes symptoms similar to other root problems.

A rootbound plant has been in the same container for too long. Roots wrap around the edges and “choke” the plant.

Rootbound plants often droop, appear yellow, get nutrient deficiencies, and stay small. Even if you’re caring for them perfectly!

If you see tons of white roots when transplanted, that means the plant was in that container too long

When this happens, the main solution is to transplant the plant into a bigger container. Another solution is to grow in fabric pots or air pots. These types of pots let air in from the sides, killing the circling roots (“air-pruning” them) and prevents the plant from getting rootbound for months.

To help a rootbound plant, transplant to a bigger container with fresh potting mix

Or start with air pots or fabric pots in order to prevent plants from getting rootbound at all

Heat Stress

If plants are experiencing a lot of heat, it can make leaves droop and/or curl. Some strains can handle a lot of heat, while other strains tend to droop when it gets warm.

Heat can cause leaves to curl up

Light Burn

Plants can get light burn (sort of like a sunburn) even if the temperature is completely under control. The symptoms are usually concentrated close to the grow lights. Sometimes this can cause leaves to claw and curl downwards.

Light burn can cause the leaves closest to the light to turn yellow

Learn more about light burn

Bugs & Pests

Often a bug infestation caused general plant unhappiness, but these are some of the most likely to cause curling or clawing leaves.

Broad Mites

Usually, you can’t see broad mites because they live inside the plant. The main symptom of an infestation is strange leaf curling that is specific to this pest, as well as “wet” looking leaves.

Hemp Russet Mites

Hemp russet mites can also cause drooping and other strange symptoms, but the bugs are so small many growers don’t realize what they’re dealing with.

Hemp russet mites cause drooping and yellow mold-like growth on the tops of plants

Fungus Gnats

Fungus gnats look like tiny flies buzzing around your topsoil. Although a few fungus gnats won’t really hurt your plants, a big infestation can damage the roots, causing symptoms similar to other types of root problems.

What does pH have to do with nutrient deficiencies?

10-Step Quick Start Guide to Growing

The post Why are Leaves Curling or Clawing? (“The Claw”) appeared first on Grow Weed Easy.

Are some or all of your cannabis leaves turning yellow? Maybe your yellowing leaves also have other symptoms like spots, curling, wilting, brown patches, etc. Marijuana plants may get yellow leaves for several different reasons, which means it can be hard to figure out the true root of the problem!

Today I’ll break down the 10 most common reasons your weed leaves turn yellow, and I’ll show you how to make your plant green again.

10 Most Common Reasons for Yellow Leaves

1. High or Low Root pH
2. Poor Watering Practices
3. Nitrogen Deficiency
4. Light Burn / Light Stress
5. Heat Stress / Cold Shock
6. Magnesium Deficiency
7. Iron Deficiency
8. Not Enough Light (especially seedlings)
9. Bugs or Pests
10. Bud Rot

When Not to Worry (Pictures of Normal Yellow Leaves)

These yellow leaves with green stripes in the margins are caused by high pH at the roots.

10 Causes of Yellow Leaves (From Most to Least Common)

1.) PH is Too High or Low at the Roots

Whether you’re growing cannabis in soil, coco coir or in hydroponics, high or low pH at the roots is the most common reason to see yellowing and other nutrient deficiencies. Cannabis plants have a difficult time absorbing nutrients when the pH is in the wrong range, resulting in nutrient deficiencies even if the nutrients are actually present near the roots.

Symptoms

• Yellow or other oddly colored leaves
• Spots, stripes, or patches
• Burning around the edges of leaves
• In fact, almost any nutrient deficiency can be triggered by incorrect pH

What is the Correct PH?

Growers who don’t make sure their pH stays in the right range will often run into nutrient deficiencies, even if they’re starting with a pure source of water and good soil.

• Soil Optimum: 6-7 pH
• Coco / Hydro Optimum: 5.5-6.5 pH

How to Fix

• Use a kit or PH Pen to test the pH of the water before you give it to your plants, and adjust if necessary by adding an acid or base to your water
• Learn How to Fix Incorrect pH.

These symptoms look like nutrient deficiencies but are actually caused by incorrect pH.

Most water sources contain enough copper (which the plant needs in very small amounts) so copper deficiencies like this one are almost always caused by incorrect root pH.

Zinc deficiencies (pictured below) are the same way. They are almost always caused by incorrect pH.

Another common culprit of yellow leaves from incorrect pH is a potassium deficiency. Cannabis plants love lots of potassium, especially in the flowering stage, but nearly all cannabis-friendly nutrient systems contain plenty of potassium. If you’re adding nutrients to the water, this deficiency is almost always the symptom of a pH problem.

This is also a potassium deficiency, even though it looks a little like nutrient burn (too high levels of nutrients). The main clue is the yellow striping on the leaves, which tends to get worse over time until leaves are mostly yellow. Another clue is the brown tips go in further than typical nutrient burn.

Stripes on the leaves (click for close-up) indicates that this is not a Nitrogen deficiency, even though the symptoms are similar. In this case, the symptoms were caused by the pH being way too high, combined with a bit too much water at a time.

2.) Poor Watering Practices

It’s much more common to over-water than under-water cannabis plants, and the symptoms are very similar. In either case, the solution is to learn how to water your plants exactly the right amount at the right time!

Symptoms of Poor Watering Practices

• Droopiness (it’s normal for plants to droop a little before the lights go out, but you know the drooping is a problem if it’s already happening at the beginning of their “day”).
• Odd problems and symptoms from poor water practices including yellowing and sometimes other deficiencies.
• Droopy leaves – Droopiness is usually caused by either…
  • Overwatering – leaves seem “fat” and swollen with water. Often you’ll have a feeling you may be overwatering your plant, especially if it’s a small plant in a large container.
  • Underwatering – leaves often seem “papery” and thin because they don’t have any water inside them. Chronic underwatering leads to overall yellowing and deficiencies.

How Do Cannabis Growers Get It?

• Young plants are extra sensitive – Overwatering is most common with young plants since they still have small, weak root systems.
• Too much or too little water at a time – You can hurt plants by giving too much or too little water at a time, and you can also cause persistent droopiness by watering too often or too infrequently
• Bad soil with poor drainage can cause the symptoms of overwatering even if you’re watering the plants perfectly!
• Small plants in big containers are easily over-watered.
• Big plants in small containers are easily under-watered.
• Not checking on plants – Growers who spend long periods away from their plants and/or don’t pay attention to their watering needs are much more likely to run into problems with droopiness.

How to Water Your Plants Correctly

• Good grow medium – Start with good soil or coco coir.
• Right size container – Make sure plants are in the right size container for their size.
• Pay attention if you notice drooping.
  • If plants start drooping after you water them, you’re overwatering.
  • If drooping plants perk up after watering, you’re underwatering.
• Learn how to water your plants perfectly every time.

Overwatering

Chronic overwatering can sometimes cause unusual deficiencies even if the pH is spot on, like this plant grown in muddy soil. The biggest sign that these symptoms are caused by overwatering and not pH (or something else) is that the plant is always droopy.

Another example of a deficiency that’s actually caused by overwatering (notice how this seedling is also droopy)

Chronic Underwatering (Relatively Rare)

Most growers tend to overwater – not underwater – their plants. However, if you’re spending long periods away from your plants or the containers are drying up in less than a day or two, it may mean that your plant needs to be watered more often, or be given more water at a time. It’s also more common to under-water when plants start overgrowing their pots.

It can be difficult to diagnose chronic underwatering because problems may look like nutrient deficiencies. Your main clue is that plants perk up every time after you water.

Learn more about underwatering cannabis plants.

3.) Nitrogen Deficiency

Symptoms

• Pale leaves – Plants tend to be lime green or pale all over, even though the leaves appear healthy without stripes or spots
• Bottom leaves turn yellow – Yellow leaves tend to appear toward the bottom of the plant
• Yellow leaves fall on their own – With a nitrogen deficiency, yellow leaves feel soft and are easily pulled off (in fact they usually fall on their own). If a leaf feels very stiff or is hard to pull out, that means it is not a Nitrogen deficiency and actually something else.

How Do Growers Get It?

• Used up nutrients in soil – Affects plants that have “used up” the nutrients in the soil, which can happen after the plant has been in the same container for several weeks or months.
• Need to increase the amount of nutrients in the water – A nitrogen deficiency can happen in coco or hydro when the grower isn’t providing any extra nutrients (since there is no Nitrogen contained naturally in plain coco or water).

It is very unlikely you have a true Nitrogen deficiency if you’re providing your plants with the recommended amount of cannabis nutrients in the water.

How to Fix

• Give good nutrients – Easily remedied by giving plants a regular base plant nutrient from basically any cannabis-friendly nutrient system
• Transplant to new soil – In soil, growers can transplant their plants to a new container with fresh soil (if they don’t want to add extra nutrients to the water).
• Learn more about Nitrogen deficiencies.

A cannabis plant turns pale or lime green all over (left) when it needs more Nitrogen. A healthy plant appears medium green (right).

This plant is on the verge of a Nitrogen deficiency. This is indicated by its overall pale color, even though all the leaves look healthy without spots or stripes. Cannabis leaves should not be lime green or pale, or the plant tends to grow more slowly!

Here’s a close-up of a Nitrogen-deficient leaf near the bottom of the plant. Nitrogen-deficient leaves are soft and look/feel wilted.

If you have a Nitrogen deficiency, the yellow leaves will start falling off on their own.

Did You Know? Oddly enough, too much Nitrogen can also cause yellow leaves, though the rest of the leaves will be clawed and a deep dark green instead of pale.

Too Much Nitrogen (Nitrogen Toxicity)

4.) Light Burn

Symptoms

• Yellowing appears most on the parts of the plant closest to the light.
• Yellow leaves do not pull out easily, even if the whole leaf is dead
• Light burn often takes a few weeks to develop and is most common once the plant is past the 6th week of the flowering stage (when plants aren’t making many new leaves to replace old ones).

Cannabis light burn usually affects the top leaves closest to the grow light instead of affecting the plant evenly.

How Do Growers Get It?

• Light burn is when your leaves are working too hard for too long, causing them to die early.
• Even if the temperature is in a good range, your plant can still get light burn if the grow light is too close. It’s kind of like how skiers can get sunburned even in freezing temperatures because of all the sunlight reflecting off the snow.
• Light burn is most common with powerful lights like HPS/LED/LEC.
• It’s also common when switching to new bulbs (which are stronger than old bulbs) or when there is no glass between the bulb and your plants.
• Some plants are more sensitive than others, and you may have one plant suffering from light burn while the others are fine. That can make it harder to diagnose the problem since some of your plants are thriving in the same environment!

Light burn symptoms can be different from plant to plant, but they always seem to happen mostly to the parts of the plant that are closest to the light

How to Fix

• The best way to fix light burn is to move your grow lights further away, or bend over the affected plants so they’re further from the light.
• When in doubt, always follow the manufacturer’s recommendations when it comes to how far away to keep your light from your plants! This is especially important for growers who utilize LEDs.
• Learn more about cannabis light burn
• How far away should I keep my grow lights?

5.) Temperature Problems (Heat Stress / Cold Shock) 

• Yellow or burnt leaves near the light
• General yellowing of upper leaves
• Leaves start “turning up” at the edges, or forming “tacos”

How Do Growers Get It?

• If you put your hand where your plants are and hold it there for 30 seconds, is it too hot to be comfortable? If it’s too hot for you it’s likely too hot for your plants.
• Although relatively rare indoors since most growers struggle with heat instead of cold, a temperature under 50°F (10°C) can also cause pale or yellow leaves. Some plants will even die if it hits freezing temperatures! Placing grow containers directly on concrete in a basement can kill them with cold overnight!

How to Fix

• You should be able to pass the “hand test” (hold your hand where your plants are and make sure it’s not too hot). If it’s too hot for you, move the light up and further away from the top of your plants.
• You should correct the temperature if it’s under 60°F at night or above 85°F during the day.
• Make sure there is good air circulation in the grow space, to prevent hot spots.
• Your plants will be more resistant to cold if you keep their roots warm, so make sure to keep your containers off the cold floor (or if outdoors, you might consider covering your plant roots at night!)!
• How do I control temperature?
• More About Heat Stress

This poor plant was decimated by a heat wave – it went through several days of 100°F+ temperatures! Luckily the buds were still great 🙂

Too much heat can cause the edges of leaves to curl upwards and make “tacos”.

Sometimes extended periods of high temperatures cause spots and other odd symptoms in addition to yellowing.

Cold Shock

This plant was exposed to temperatures under 40°F (5°C) at night, causing all the newest growth to turn so pale yellow it almost looked white!

6.) Magnesium Deficiency

Symptoms

• Yellowing in between the veins on leaves, often located lower down on the plant.

How Do Growers Get It?

• A magnesium deficiency is almost always caused by incorrect pH though if you’re using heavily purified or soft water (such as RO – reverse osmosis – water) you may need a Cal-Mag supplement to make sure your plant is getting enough magnesium.

How to Fix

• First, check the pH. It should be in the 6.0-7.0 range for soil growers and 5.5-6.5 for everyone else.
• If a Magnesium deficiency persists, consider getting a CaliMagic supplement that is made for plants (you should always add Magnesium and Calcium at the same time because these two nutrients work together in the cannabis plant).
• Learn more about Magnesium deficiencies

With a magnesium deficiency, the yellowing happens between the veins of the leaves, while the veins stay green.

Sometimes Triggered by Old Age / Natural Senescence / Light Deprivation

• It’s actually normal if you only see these symptoms on a few leaves at the bottom of the plant that are no longer getting any light. The plant eventually “gives up” on old leaves if they spend days or weeks without light, which often happens to the lowest leaves as the plant gets bigger. This may look like a magnesium deficiency.
• If this is the case, the leaves often seem droopy, limp, and tired. These leaves don’t “stick straight out” like normal leaves because the plant isn’t wasting resources by putting energy into them.
• This is most common when using relatively weak grow lights like fluorescent lighting or CFLs, since the light doesn’t easily reach the bottom of the plant.
• Therefore this symptom is only something to worry about if it’s happening on leaves that are still getting light, or if you’re seeing the symptoms on many different leaves instead of just an occasional leaf here and there.

7.) Iron Deficiency

Symptoms

• Iron deficiencies are unique because the yellowing always affects the newest growth; it does not happen to older leaves that are already green.
• New leaves usually come in completely yellow.
• Unlike most other nutrient deficiencies that cause yellowing, yellow leaves from an iron deficiency will usually turn green, starting from the outside edges and working inwards.

How Do Growers Get It?

• Unless you are using RO or very purified water, an iron deficiency is almost always caused by incorrect pH. This is because cannabis needs very little iron, and most sources of water already contain trace amounts of iron.

How to Fix

• The pH being too high or too low is the most likely cause of this problem. Bring your pH into the correct range and iron deficiencies will just go away.
• If using purified water or water that doesn’t contain much natural iron, you may need a Cal-Mag supplement that includes iron like CaliMagic. You see these three together because Iron, Calcium, and Magnesium work closely together in the plant. You never want to supplement your plant with extra iron without also adding the correct ratio of Calcium and Magnesium at the same time, or it may cause other types of deficiencies.
• Learn more about Iron deficiencies

Iron deficiencies cause the middle and newest leaves to turn yellow, but they will slowly turn green as the plant gets older

8.) Not Enough Light (Seedlings)

When a shell first cracks, the round leaves inside are actually yellow. They only turn green once the plant starts getting enough light.

Note: Adult cannabis plants without enough light won’t grow well either, but they likely won’t have yellow leaves. In fact, adult cannabis plants that are getting relatively low levels of light will actually turn dark green since they aren’t using up nutrients for photosynthesis (the extra unused nutrients get stored in the leaves, causing them to appear darker).

How Do Growers Get It?

You know your seedling needs more light when…

• Seedlings are tall with small leaves
• There is a lot of nodal spacing (stem between each set of leaves). Seedlings look “stretchy”.
• Leaves stay yellow or pale green

How to Fix

• The solution for pale, tall, stretchy seedlings is to add more light!
• Learn more about different grow lights as well as how to upgrade your light system

This seedling is yellow and “stretching” because it needs more light

9.) Bugs or Pests

Many different types of bugs or pests can stress your plants, causing them to develop yellow leaves.

Symptoms

• You can actually see bugs or eggs
• Yellowing leaves, especially when combined with spots or bite marks
• Overall lack of vigor

How Do Growers Get Pests?

• Track them in from outside
• From visiting another grower’s plants
• Getting an infected clone or plant (sometimes there are a few tiny eggs you can’t see!)
• Certain things like overwatering, lack of cleanliness, and poor air circulation make your garden a bigger target and a better home for bugs, making it easier for an infestation to take hold and stick around.

How to Fix

• Unless you 100% trust the grower and their growing practices, never ever visit another grower’s garden or adopt clones from them. It can be incredibly difficult to get rid of bugs that are already specialized at surviving on cannabis plants!
• Avoid going straight from outside to your cannabis plants, especially if you’ve spent time in a garden.
• Make sure there is a screen to stop bugs if your plants are getting fresh air from outside.
• Identify your bugs and get rid of them!

One of the most common pests that can cause yellowing without really any other symptoms is fungus gnats. These tiny winged creatures hang around your wet topsoil, and are most likely to appear if you’re overwatering your plants. Although the adults don’t attack your plants, their larvae feast on the roots, which can eventually cause yellowing, especially on small or weak plants.

A bad fungus gnat infestation can damage or even kill your plant!

Another common pest that may cause overall leaf yellowing is spider mites!

But any time a plant has an infestation, you may notice the leaves start yellowing regardless of the type of bug. You should be very concerned if you also see spots!

10.) Bud Rot

If yellow leaves appear overnight on just one or a few of your main buds, inspect the areas closely! Sometimes this is caused by bud rot at the base of the leaves.

Symptoms

• Yellow leaves on select parts of the biggest buds
• Yellowing often appears overnight
• Yellow leaves usually easily fall right out
• At the base of the leaf, you can see white, gray, or brown mold growing on the inside of the cola

How Do Growers Get It?

• Humidity above 60% RH
• Lack of air circulation/breeze
• Cool temperature – bud rot thrives around 60-70°F
• Bushy plant (too many leaves) in a small space like a grow tent
• Outdoors in rainy, cool, or humid weather

How to Fix

• Keep humidity under 50% RH during flowering if possible
• Keep the temperature above 65-70°F at night if possible
• Make sure there’s lots of air circulation around all the colas and through the plant
• Defoliate a very bushy plant, especially if it’s getting close to harvest time
• Learn how to prevent and treat bud rot!

Sometimes Yellow Leaves Are Normal!

Sometimes marijuana leaves turn yellow for totally normal reasons, including…

First Leaves Turn Yellow – Normal

After your plant has grown a few sets of leaves, it’s very normal for the first few sets of leaves to turn yellow and die, especially if they’re not getting light anymore. You will almost always lose the round cotyledons, the single-finger leaves, and the three-finger leaves (the first three sets of leaves).

This vibrant young cannabis plant is healthy and growing over an inch a day

However, if you look closely at the bottom of the plant, you can see the three bottom sets of leaves have turned yellow and are dying. This is normal. The plant does not hold onto these baby leaves for long!

Single-Finger Leaves (plus the tiny round cotyledon leaves)

Three-finger leaves

When just the first 3 sets of leaves turn yellow like the example above (leaves with three fingers or less), it’s not something to worry about as long as the rest of the plant is green, healthy, and growing fast.

You don’t normally see these in pictures because most growers remove them 🙂

The Plant is Ready to Harvest – Normal

Often plants will have a few yellow leaves by harvest time. This is completely normal and nothing to worry about as long as you’ve ruled out bud rot and most leaves seem healthy.

Mutation – Cosmetic (Usually Not Harmful)

Occasionally you may see mutations or natural variation that results in parts of leaves being yellow. The general rule of thumb with any unusual leaf symptom is if the rest of the plant is green, vibrant and healthy, there’s usually nothing to worry about.

What does pH have to do with nutrient deficiencies?

10-Step Quick Start Guide to Growing

The post Why Are My Cannabis Leaves Turning Yellow? appeared first on Grow Weed Easy.

When I was first learning about how to grow cannabis, I learned about the importance of pH to prevent nutrient deficiencies. But sometimes your pH is in the recommended range and your marijuana plants leaves are still showing signs of nutrient deficiencies.

What else besides incorrect pH causes nutrient deficiencies in cannabis plants?

Basically, when it comes to cannabis plants, your plant starts experiencing nutrient deficiencies if the pH is too high or too low at the roots. This is because the chemical structure of nutrients actually changes at different pH levels, and some versions are easier for the plant to absorb than others.

By giving your plants good cannabis nutrients and managing the pH, you’ll be able to prevent most nutrient deficiencies, ensuring your plant grows as fast and healthy as possible.

But what do you do if you’re using good nutrients and the pH is right but you’re still getting nutrient deficiencies?

When it comes down to it, nutrient deficiencies usually start at the roots, whether it’s pH or something else. This looks like a nutrient deficiency, but it’s actually caused by overwatering.

One of the most common reasons to see deficiencies when the pH is correct is the plant is being over or under-watered, which can also be related to the drainage of the grow medium and the container your plant is in. When the plant isn’t getting the right ratio of water and air at the roots, it will tend to start showing deficiencies even if everything else is right. Other issues with roots are also common culprits.

Causes of Most Nutrient Deficiencies

• PH is too high or too low ← Most Important!!! But if you’re on this page you’ve probably already got this covered.
• Not enough nutrients overall (here are recommended cannabis nutrients)
• Over-watering
• Under-watering
• Pot is too big for the size of the plant
• Plants are rootbound (been in the same pot too long)
• Too hot (and rarely too cold)
• Bugs or pest infestation

Note: Basically anything that makes your plant droopy is likely to cause nutrient deficiencies, too.

Although pH and watering practices are probably the most important thing to pay attention to, there’s more than just pH as far as your plant roots are concerned. The “alkalinity” of your water is also important. Alkalinity is related to pH, but it is also its own thing. In a way, alkalinity measures how much “stuff” is in the water that causes the pH to go up. And this also affects nutrient absorption.

If you’re still having trouble after going through the steps above, and your pH is in the right range…

• If you have “hard” water, you should generally aim for a slightly lower pH (aim for around 6.5 pH for soil and 6.0 pH for coco or hydro).
• If you have “soft” water, you should generally aim for a slightly higher pH (aim closer to 7 pH for soil and 6.5 pH for coco or hydro).

I hope that helps some people dial in the correct pH based on their starting water.

How to Fix Incorrect pH Without Flushing – Do this if possible!

Why Should I Flush My Sick Marijuana Plants?

The main reason to flush your sick cannabis plants is to try to correct something wrong at the roots. Flushing means watering your plants with lots of plain water at once. All that extra water leaches out extra nutrients or salt buildup in soil or coco coir. Flushing can also be used to address nutrient deficiencies caused by incorrect pH near the roots. However, flushing is stressful for plants, so it should be avoided unless you have no other choice. This tutorial will teach you when to flush your plants, and when you should address your sick cannabis plants a different way.

Flushing plants with lots of water makes them droopy, and should be avoided if possible. Take good care of plants and you’ll never need to flush. But when it comes to growing, things don’t always go according to plan! If that happens, this tutorial will guide you on what to do.

The following cannabis plants were flushed due to nutrient deficiencies.

When flushing is done properly, your cannabis plants should quickly bounce back and start growing healthy without deficiencies.

• Flush Out Additives That Made Plant Sick – It’s important to flush a plant that has been watered with something that has made it sick, for example if it is losing leaves because it was recently watered with a pesticide, nutrient or supplement that was too strong.
• Leach Out Time-Release Nutrients – If transplanting isn’t an option, sometimes a grower will flush a plant that is being grown in soil with “time release” nutrients (like Miracle-Gro soil). This idea is to try to leach out extra nutrients (specifically nitrogen) before the flowering stage begins. Too much nitrogen in the flowering stage can give buds a “green” taste as well as actually prevent buds from getting as big as they normally would. Since time-release soils slowly releases nitrogen for months it’s important to flush that out before your plant starts making buds.

If your cannabis plant gets sick the day after you add a new supplement for the first time, you should probably flush your plant to “start fresh” at the roots.

Which Growers Should Flush Their Plants?

Flushing sick plants is for…

• Soil
• Coco coir
• Other soilless mediums

Flushing sick plants is NOT for…

• Hydroponic or DWC grow setups – if you have a nutrient or pH problem, just change the reservoir so it has exactly what you want

How to Prevent the Need to Flush Your Plants

• Start Nutrients at 1/2 Strength – When using a new type of nutrients for your cannabis plants, it’s a good idea to start at 1/2 strength at first. It’s also a good idea to start any pesticides or supplements at half strength until you see how your plant reacts.
• Give More Nutrients to Pale Plants – Increase nutrient dose if the overall plant is starting to look pale or lime green.
• Lower Nutrients for Dark Leaves or Nutrient Burn – If you notice plants are getting dark green in color, try lowering nutrient levels or giving plain water every other watering until their color has improved. If you notice brown crispy tips on the leaves all over the plant, that’s another sign of the plant overall getting too much “stuff” (whether nutrients or supplements) in the water. If the dark leaves or brown tips are the result of too much nutrients, usually you’ll see these symptoms all over the plant instead of just a few leaves.
• Check pH for Other Nutrient Deficiencies – If you seen nutrient deficiencies like yellow leaves, spots, or brown markings, the first step is to check and adjust the pH of the water you give your plants. Maintaining the right pH is the #1 way to prevent nutrient deficiencies. Simply do this one check when you water, and you’ll dramatically reduce the chance you’ll even need to flush (pH being too high or too low is the main reason to flush plants). Learn more about nutrient deficiencies.
• Reduce Light Levels on Sick Plants – When plants are sick, try moving the grow light up a few inches or even a foot. This will help your plant recover more effectively from many nutrient problems, whether you end up flushing the plants or not.

Try to prevent nutrients problems before they happen so you never need to flush!

How to Flush Sick Cannabis Plants

1. Make up water with low levels of nutrients (1/4 strength or seedling dose). You want to take out the bad and replace with the good.
2. Give 3x the pot size – Use enough water so that you’re giving the plant 3x as much water as the volume of the pot. It may take a little while. Remove all runoff water immediately, you don’t want your plant to suck the bad stuff back up!
3. Give regular strength nutrients at the end – Make up one last batch of nutrient water at regular strength, and give this to your plants. You are replacing what you took out with what you want to be there – fresh, pH’ed nutrient water!
4. Make sure there is a fan blowing over the top of the growing medium to help it dry out so plants don’t get as droopy from being overwatered. There should be plenty of air circulation in the grow space, with access to lots of fresh air.
5. Raise your grow lights up a few inches while your plant is recovering. Your plant definitely needs plenty of light, but you don’t want to make it work too hard during the recovery period.
6. Wait a few days for improvement – Although your plant may get droopy at first, you should start to see improvement within a few days. Try not to water it again until the top inch is starting to dry. It’s not recommended to flush a plant two times in a row. After the first flush you should have flushed out what was hurting the plant in the soil. At this point, it’s time to give your plants some TLC while you get things back on track.

How to Fix Incorrect pH Without Flushing

1.) Determine your target pH

• Soil: 6-7 pH
• Coco: 5.5-6.5 pH

2.) Collect runoff

Give your water at the correct pH, and collect runoff water out the bottom. Is the pH too high or low? If the pH is higher or lower than the correct range, don’t panic! At the very least you’re already giving your water at the correct pH from on top. That will help the plant stay healthy while you fix whatever is going on at the roots. Now, onto fixing your pH.

3.) Start fixing the pH the next time you water your plants.

If you already have major nutrient problems, you might consider flushing as stated above. But if you don’t see problems yet, or if you only see just a little bit of leaf discoloration or yellowing, there’s no need to flush. Flushing is very stressful for plants and may prevent them from recovering as fast as they could, so it should be avoided if possible.

Most of the time, if your runoff pH was too high or too low, it’s better to wait until your next watering to start correcting it.

4.) Always give water in the correct pH range, but at the opposite end.

Next time you water your plants give water in the correct range, but at the opposite end of the range to start trying to get it to move in the other direction.

If your runoff water is coming out at 4.5 pH, it means you should water your plants at the high end of your desired pH range. So for soil you would water your plants at 7.0 pH, and with coco you’d water your plants at 6.5 pH.

This ensures that your roots are getting some amount of nutrient water at the correct pH, while also starting to leach out whatever is in the growing medium that’s dragging the pH down.

5.) When pH of water going in and out mostly match, you’re good!

Eventually, your pH is going to start coming out the bottom of the plant in the right pH range, even if it takes a few weeks.

Collect the runoff water and check to make sure the pH isn’t too high or low. Proper pH stops most nutrient deficiencies!

I’ve found that correcting the pH following this process seems to stop most nutrient problems within just a few days, while preventing your plant from getting stressed from a true “flush.”

I wish I had known this before I started growing. I’ve done too many unnecessary flushes and unintentionally stressed out my plants. I hope this help guides you to better results in your cannabis growing journey.

Happy growing!
