Having a little problem with my clones. I transfered the rooted clones into the hydroton and net pots and put in the bubble buckets. They went from flouresent lights to a 400w hps wich is about 3 feet above them. They have been in there 6 days now and I am seeing roots come through the pots but my plants are starting to droop and yellow in the center a bit. I have seen no new growth besides roots.I am using GH nutes and the lucas formula at 50%. PH is fine and temps are good. Do you think its the hps causing heat stress? What should I do?
