Can you help diagnose

I started watering it with regular water and clipped the ones like this off I am using a 3 gallon smart pot about half way full of soil. Could it be because lack of spil

picture of entire plant please

Maybe calcium or iron deficiency. But, yes. We need a full plant pic. Preferably in good light. It's the only way we can really help diagnose the issue.

If its yellowing out, no food isnt the best idea usually. Id keep feeding, with micros. And then give more specs on the grow. Lights used, feeding and feeding schedule along with feed used NPK values, ppms, soil type, humidity p, temps, ect..
