I switched to 12/12 a little over three weeks ago and have had no problem until now. On top the white pistols are turning already and gets slightly better going down. I got a 400 hps overhead. Only two going right now. A week ago it was fine, and I wouldnt be worried except I don't see new ones growing in. The light is 12 inches from top and ample ventalation. Ideas? I have pics I'll post in the morning.. Ideas?
