Turtle, as long as their loving their clf's, let them stay. If they start looking a little pale green, give them some very weak nutes. Are you spraying them? I always mist with weak ferts. Two of the clones I put in the dark for a few days, the centers turned yellow and the outter leaf was still green. I moved this pair next to a window and it greened back up.

If you give them light right now, they will burn up all the sugar stored in the leaves and turn yellow and die. Don't give them bright light until they develop roots. When I start to see roots, I give them a weak nute.

Hang in there Mand. Some of us have more experience than others (we make mistakes too) and some of us just have too much time on our hands. (That would be me.)
