Clones wilting help?

I have clones in a DIY humidity dome that i made 4 hours ago.

4 out of 6 of my clones were wilting and i thought that the humidity dome would solve the problem.

Its probably gonna take a day or more to get them back on track.

Can someone help me out and give me some advice .

ASAP please.

How hot is it getting in there?

more info needed.

lights used for clones?
you should really use clear plastic for a dome.

ph of your water going into the cubes?
