Okay, here's some advice
1) Use low power, blue spectrum lights to help root the clones. A couple CFLs or flouros will do.
2) Do NOT keep feeding them. They are not extracting anything from the soil right now, so you're just building up salts.
3) Foliar spray them with a bloom solution (high p), but LOW ppms, to encourage root growth. Better yet, get rapid start 0-2-0 with B1 to help with this. Some maxicrop seaweed is awesome too.
4) Cover them to increase humidity, vent it a few times a day or use a dome with a vent.
5) Don't move up to big lights until they have a healthy root system.
Those plants probably won't make it, and if they do, they will be really stressed. I recommend buying clones in a medium where you can clearly see the root system.
