im going to flower ina bout 2 weeks. i got 4 skunk # 1s all about 24 inches or bigger vegin under 400 mh. the problem is when they were just little clones (all 4) they have been having this strange curling of the edges up towards the center median of the leaf. My plants look great except for that. nice lush dark green color, bigger stems, noticeable growth every day, etc. I accedentally added a dose of 5-45-15 with my normal 6-4-4 a couple weeks ago and im wondering if that is the reason theyre looking so good now. and by the way ive had these clones since january 22nd and for a while they were stunted. But arent one of those macro nutrients needed for fending off disease? either phosphorus or potassium. All 4 are showing the same symptoms so you would think that was a clue to solving this mystery and maby i should start adding 5-45-19 although they wont be flowered for a couple of weeks. what do ya think? will adding more p or k help plants that become sick like mine? This is the best specimen that shows the leaf edges curling.
