I am growing a Barneys Farm LSD strain in FFOF soil with fox farm nutes. the plant is 5 weeks from sprout and 2 weeks from topping. ever since the 2nd week started the plant has had some nasty looking yellowish-green blotches all over and eventually started developing ugly deformed leaves. I first thought it was from giving it the Fox Farm "Big Bloom" as recomended in week 1. But as I adjusted the nutrients I haven't seen a healthy looking leaf since. I keep it under a 400w hps on a 18/6 light schedule. I also use tap water. I tried epsom salt on a couple waterings to no success. It is starting to look lifeless and is falling behind in terms of height, girth, and foliar output. I will post some pics. please help me save my plant.
