Hey guys, this is the third problem post in the past month, I don't know how to fix it!? first time grow, It started off as over nutrient feeding, then I over corrected and underfed. Now I'm somewhere in the middle I guess and I don't really know what to do. I'm growing 3 bag seed plants out of a grow tent in a closet. They are all in 2.5 gal pots of soil. I did a slight flush yesterday, I used 1 gal of water with half nutes for each plant. Plants are still yellowing and dying! It starts with fan leaves on the bottom of the plant and it just spreads up! Anyone, please tell me step by step how to fix this. I've put about a month of stress on these plants and I don't wanna have to waste a harvest for some petty problem I cannot seem to figure out. Help is appreciated
