Yellowing older leaves
Flaviostarted grow question 5y ago
Is this a nitrogen deficiency? It's happening just on the 3 bladed leaves of the plant on the left. The plants look overall healthy, at least I think

Light burnI've got what I think is light burn. I can't dim or raise my LED lights (300w), but I'm currently running them 24/0. Would switching to 18/6 help? Or would it help to take the burned plant and have it out in natural light during the day? I'm growing autos and they're flowering.Week 11
