It's normal for lower sun leaves to die off as the plants begin to mature, I used to stress over this as well but there isn't really anything you can do about it. The tops look fine so I think you're OK. Have you checked for mites? They will cause yellowing and necrosis as well.
Purple Daddy Reviewed by Purple Daddy on . I'm stumped Greetings all, Iā??m humbly asking for some help on what may be going on in my room. This is a mother/clone only room and Iā??m having some issues with the fan leaves on the bottom of the plant going yellow, necrotic spotting, and withering. Iā??ve been doing a little bit of supercropping and LST but all of that looks fine. Two of the pictures are pictures of lower fan leaves and the other two are from the top of the crop which looks much better. 276904276905276906276907 Any help is Rating: 5
