Its definitely not over watering. I have been very careful not to do that. Its not temps either. Day time temps never top 79F and night time temps run ~68F. As for the misting, I just did that to see if they would perk up with a little foliar water and less light. I know that some drooping late in the light cycle can be caused by excessive transpiration and that the plant is tired and is using water faster than it can replace it. I'll drop the lights today after they have been on a few hour. As for the soil, its all I have access too beside manure and topsoil and I am not brave enough to start mixing my own soil. I have read all about MGs pH problems and over-nuting issues, so I mixed dolomite lime in with my soil and I take it easy with the water, only every 2-4 days when its dry, they I water until the pot feels heavy but doesn't run off.
