Hey guys/gals I don't have a digital camera atm, or I would post a couple pictures. I have 3 Blue Mystic plants growing under a 400w HPS setup in an extra closet that I have. I just noticed tonight on the largest one that the edges of a couple of leaves are curling up a little. Would this be caused heat etc etc? Can anyone show me or confirm/deny this? I have the light about 15 inch from the top of the largest plant. Any thoughts would be highly appreciated. Thanks in advance. This is my first grow They are in FFOF with no nutes yet. Just watered them yesterday. They are also on a 24h light as of right now. 400w HPS like i said. Oh, also they are in three gallon buckets right now too. I also have a question about Topping. When should I actually start it? after how many nodes? Should the one i am actually cutting be a certain size before i cut it? What i mean is should i remove it as soon as i see it or should i wait for it to grow some then cut it? Hope that makes sense.
