I think i have nitrogen toxicity in my flowering plants (3/4 weeks in). I've used organic slow release fertiliser which worked great for the veg stage but now i'm thinking its giving the plants too much nitro for flowering as i'm getting the claw on my bud leaves. The problem is i can't just flush them because of the slow release stuff. Does anyone have any suggestions? Would it be worth transplanting them into fresh soil or would that stress them too much?
