What'd you do . . . skip school the day the teacher taught the class that clones need to be covered.
You can make a tent out of a plastic bag, if need be. Let it breathe a couple times every day. As it roots, you'll notice it can take more and more time out of its' "tent" until it no longer sags when left out in the air. You could remove a few of those leaves too. Next time try not to get so many. I might start w/2-3 preferably still growing (not full size) leaves.
I think clones do best 18"/24" away from your light.
