3 Clones not watered for 8 hours, will it die?

The plant is realllly dropped out, and really looks dead. will these plants revive?

I use homemade aero cloner, and the pump got clogged so there was no water going to the roots.

These were ROOTED ClONES

a clone with roots wouldn't 'drop out' after only going 8 hours w/o water. something else is going on.

Thanks for the reply!

Im pretty sure it was the water, the 1 inch RW cube it was in was a little dry as well. it was COMPLETLY dry when i checked. and the plant was lifeless..

Anyone? lets say, the PPM of the tap water is 750 (which it is) and i want to feet a plant 300PPM of nute. should the PPM be 1050?

Will this burn the plant? since only 300PPM of nute is being used for a young clone?

and the 750PPM is not NUTE concentrate?
