I have noticed that a few of them are getting a bit too hot from the 1000hps at first sign of water leaves also. If you set them under floros just to get them going a bit it wouldn't hurt. Also if you put them under 4 bulbs, floro within one inch of the bulbs for one month, I will GUARANTEE female pre flowers 90% of the time. I am getting 100% with this method, but saying 90% just to be safe. 24/0 for one month under floros first, with them almost touching the bulbs. You'll have to move the light daily but who cares when you have a pulley system.
