Hey they are 32days old, in foxfarm ocean forest soil 5gal pots. The tops of the plants look like they are drying out? leaves are twisting and look crispy. its just the tops of the plants , with the upper leaves bout 3 rows down. funny thing is the lower ones are fine. I thought it was nute burn, ph problems. but all that is taken care of. I thought it could be my light burning it. Its 600hps air cooled (put it under them bout 2weeks ago) I got it down to bout 14-15in and I was told it could be my fan ocilating on them .. so the other day I raised it so it didn't blow on them at all. I left them alone for a few hours and when I came back they were worse!!! look at the pics I don't know what to do.. here is what they were looking like before I turned the fan up They were still looking crapy but they got worse when I moved the fan. I since then moved the light to bout 18-20in and put the fan back. What I don't understand is I keep hearing people say that they have their lights 10-12in away cuz they are air cooled.. WTF??? why cant I? could it be the white widow strain?? I dono im a newbie first grow... anyhel[ would be greatly appreciated!!!!!!!!!!!!!!!!
