labifleanswered grow question 6y ago Hey gardener, I wouldn't flush because I don't think you have too much fertilizer, I even think you don't have enough. I'm not an expert, but I know that plants need NPK and that you change the NPK dosages if you're in growth or flowering. I saw that too much nitrogen makes your plants so green that they are almost black or blue, so you don't seem to have that. Your plant looks like it had a heat shock or it's missing some P or K since your amendment is just N. Bella ciao!
