well they didnt seem to take to the HPS too well. I think I may've had the lamp too close at 12 inches (400w). I did the hand test and it seemed fine, but I later saw some bleaching and leaf curl and so have now raised the lamp to around 20 inches.
I also noticed that it seems to be the coco seedlings that are looking least healthy and this leads me to think I may have a either a slight N defciency or CalMag deficiencies. to this end, I'm going to get some seaweed foliar feed and some epson salts today.
