Is slight bleaching of leaves a problem?? I scrog so its not the big fan leaves, because I try to tuck them under bud sites. The bleaching is occurring more at the top were the bud site is about to develop. The bleaching is not occurring on all upper bud sites (8th day of flower), its only on about half of the flowers or the closest ones to the light. Im using a 600 watt hps and keeping it about 18" away. Is this ok slight bleaching ok????? Or should I move the light up higher or go back to the 450 hps, the bleaching is occurring because of the light being too close.
