Clones?

i took 5 blueberry clones and three g-13 arm. ones and i used rootone powder and put them in peat pellets. they are in a domed tray and they are sitting on top of a heating pad on low. my problem is is they are nice and warm and humid and what I'd think to be happy but only two of them are standing up the rest are all droopy and not too healthy looking. what could be my problem anyone know?

pics??????

How old are they?

id put up pics but i dont have a camera or a scanner or anything, and i probably took the cutting like a week maye two weeks ago... a few of them came out of there droopyness but two dropped reight over and then got all crispy so i just junked them. i think the peat pellets were to wet and i was misting them enough because i changed the heat setting on the warming pad thing so it would get warmer and i mist them like three times a day now instead of the usual one (if they were lucky) hahaha,
