I have 6 (now 5) white russian plants planted in 3" temporary containers. They are about a week and a half old and I just got off of work today and looked at them and one was completely limp and starting to shrivel and the other 5 are bending backwards almost like they're wilting with slighty yellowing of the leaves. They are about 5" tall and I've been watering them heavily once a day for the last 4 days. I'm using foxfarm oceanforest soil, I have a 400 watt hps that I just switched to 12/12 2 days ago sitting ~26" above the top leaves. The reflector is not air cooled but it does have glass and theres plenty of air flowing between the light and plants, with a 640cfm fan pulling old air out of the room. I don't have a camera to take any pictures but if anyone might be able to diagnose the problem by anything I've said I will greatly appreciate it. Any questions, please ask.
