seedlings

Ok so i got my seeds and planted them straight into rapid rooter plugs on 3/3/11 planted 14 seeds all but 2 have came up and most seem ok but 2 have curled cotyledons and the first true leaves are drooping then i have 1 that one cotyledon is still pointing straight up...so i guess my question is how dry am i supposed to let these plugs get before watering again im assuming the ones with curled leaves are over watered and the one with the leaf straight up isnt getting enough water...rh is 40% temps go from 80 with lights on to 70 with lights off...using a small 2ft floro fixture about 5 inches from the top of them and the 1000w metal halide is on in the same room but about 5 ft away.watering with a spray bottle and only spraying the plugs not the leaves. any suggestions or comments? i know one of the biggest rookie mistakes is over watering but im so nervous its gonna suffocate the roots if the plugs dry all the way out..will post pics in the am if needed.....

I'd just mist the plugs once a day. You can't get rapid rooters too wet unless you submerge them in water.
