Emergency Resources for Sick Seedlings!

Sometimes the hardest part of growing cannabis is getting started. 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!

At GWE, we have resources for almost every common growing problem, so make sure to always use the search bar on the side of the website if you have a specific problem.

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

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.

Seedling is Wilting or Droopy

If you notice your plant is droopy all the time, even in the mornings, it almost always means there’s something going on at the roots. It 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 temperatures.

​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!
