Grow up date

I tried to transplant some of my clones into a potting soil/foxfarm mix after they had rooted.
I've never had good luck cloning my plants ,they root but wilt from lack of water.
I use rooting gel..generic brand maybe that's the issue,i've talked to other growers about this issue and a couple ideas they said were either 1) stress from lights after transplant 2) packing the roots to tight when placing in soil.
I think I should start a hydro-system for my clones easier on the roots
