Question: Why did my plant stop growing? The tops of my plants are curling, wilting, and looking rough around the edges…
Between week 9 and 12 my plants stopped growing and the tops are looking rough. I'm growing with fluorescent grow lights (T5 grow lights), General Hydroponics nutrients, and my growing medium is rock wool.
This looks like either root or pH problems. This is relatively common in hydroponic setups where you're growing directly in rockwool, which can tend to hold too much water.
