Can anyone please tell me why my fan leaves are turning yellow? I’m on day 60 Northern Lights Auto. I been having trouble with the downward clawing of the tips of my leaves, I think she was getting heat stressed so I turned my other two lights off, they generate a lot of heat for LED lights. The last 3 waterings it’s been straight ph water. Today I gave her some supplements at 1/4 strength from what the bottle says. Now I see all these leaves turning yellow. Is this bitch that sensitive or what? PH run off water tested at like 6.12. Respectfully request any help I can get
