Why are shaking out the water? The whole point of rockwool is that it it can't be overwatered. I don't prefer the wrapped cubes for cloning, but they should work, just might take longer. Next time, skip the goop and stem prep. Use a toothpick to wally out a hole in the cubes, cut the branch, and stick directly in the cube, quickly.
As for your current problem, I'd give them a blast at the cube with a turkey baster of pH adjusted water / light nutrient solution. Crack those vents as well and ditch the misting. A little condensation on the walls of the dome is OK, but if it gets excessive, open the vents more to lower it.
85F is a bit hot. Keep in mind that those particular clones may start yellowing out before they root. Ignore it and be patient. They'll recover just fine once rooted.
Edit: Cut the wraps off, that would be better. The only reason I have ever found for cutting the leaves, is if you are cramming a lot of clones in the tray, it is best to avoid overlapping leaves. If you are using pH down to adjust, that in itself constitutes a light nutrient solution. If I add anything else, it is maybe a 1/8-1/4 tsp of maxigrow per 4 gallons solution. That may not be needed, it is just habit.
