I just bought 6 blue dream clones a little over a week ago. I immediately put them in soil and watered them. They havent grown since and are starting to turn a little yellow and droopy. I have them under a 400 watt mh but the temperature doesnt seem to be a problem. What could cause this? I was thinking possibly overwatering but im not sure. Please let me know if you know whats goin on or what i should do. Thanks.
