Why are my leaves turning yellow
ChitownCannaChicaanswered grow question 4 years ago
Hard to tell with the lighting, but thrips are bad! As stated below—- spray plants in veg with neem (right before lights out), get some sticky yellow soil bug traps, and maybe some diatomaceous earth powder for the soil. They can get out of control very quickly!
TheSlimeGrowsanswered grow question 4 years ago
The white dots are from the thrips. You should get some Neem oil, spray it on the soil and also lightly as a foliar spray.
The yellowing and browning of the leaves are probably a separate issue, it looks like potassium deficiency.

What do you think the problem could be?There’s something going on with some of these plants and I can’t seem to identify the problem so far. I have been doing a lot of research and I’m in a process of elimination at the moment but the plants growth hasn’t been affected. I will continue to try treat the problem.Week 5
