Hey everyone, I've just noticed these leaves yellowing on the new growth coming out. I'm pretty unexperienced so I'm not to sure what the cause is. Lately I've being putting them under lights indoors for a little bit as it's being really Cold where I live, so I'm not sure if this could be light burn ? Or something else like a pH problem. Any tips would be really appreciated ️️ Sent from my CPH1920 using Grasscity Forum mobile app
I’m on my first grow so don’t take my word for it, but from all the reading I’ve been doing it looks like it could be light burn. Says it generally starts at the top closest to light. Try backing light off and see if it gets better. I think I also read that nitrogen toxicity can cause yellowing one the center. But I believe that’s on new growth and there are usually other symptoms that follow. Other then the yellowing in the center plants looks healthy to me. I’d back the light off and go from there.
