how close do you have your two 1k's from your newly transplanted clones? Another thing, are you taking them straight from your humidome to the HPS's? Chances are, you are killing them with too much light. I'm no expert, but in my opinion you are providing them with too much light and their small root systems can't supply that much water to them to keep them alive under 2k watts of HPS light. Someone please correct me if i'm wrong here, don't want to pass bad info.
