I’m growing some WW auto’s in soil with a Mars Hydro FC 3000 and some off the tops have started to look like this. They haven’t been feed in a few days so I’m guessing it might be light related? Thoughts? Thanks!
How close are your lights to the top of the plant
20" Could it just be they needed watering? They have started drinking a lot more and were kind of of dry. I’ll see how they respond to being watered.
Leaves will roll like that for a few reasons. My WW do that when it’s time to turn down or raise the light . Could also be a ph issue. Check your ph and if you’re within range id move the lights up or dim them
