Cannabis plants new growth keep Turing yellow

[Lilchris1993]

Hello there, I have been growing for years and never ran into this problem until now. My plants go from bring healthy to turning yellow and scraggly. Idk whats wrong. I flushed, I checked the ppm, the ph and everything is good. Could it be a plant disease? Please help!

light stress,..
what kind of light how close?
what’s temp and humidity 24/7?
check for mites, gnats etc?

seems like some of us myself included would grow better under candle light
