Soil from my yard lol. I literally went 100% organic. From what I’ve read tho. It looks like either magnesium. Calcium or a phosphorous deficiency. And I haven’t had any problems until I fed them Sugar. But I’m also growing outdoors in Florida
Well. I’m not using any bites whatsoever. I too fed them sugar for the first time about a week and a half ago. The yellowing started 2 days ago and is progressing quick. My buds are still underdeveloped and pistols are browning like crazy.
