Is your girl in flower? If so, bottom leaves turning yellow is normal from what I have read on this forum.

Bottom leaves = mobile nutrients… my guess N but like @JaneQP JaneQP said, if it’s late in flower it’s normal if not, you either need N or pH is off and not allowing N uptake.

My guess was also PH, I have tank 2000gallons and if I need PH at least 7.3 I need to spend 100$ for advance Nutrients PH down just to adjust PH
