The humidity is around 50% all the time and I think I have over watered them a little but I don't think that would cause it. I have the grow bible and it did say something about mag. diffiency also. I guess that will be my next move. I am using fox farm organtic soil and fox farm big grow fert under a 1000 watt HPS light, (so I am giving the hole pic of the problem).
Thanks for the advice!!!!!
