Think of your plant like a straw.
When you cut a clone, there are no roots to uptake water and if the plant stays in good growing conditions, the leaves are sucking at full force and the "straw" collapses.
Yours have roots, but still small and not able to support the amount of transpiration the upper part. The bottom hole of the straw is open, but only a tiny hole and if you suck hard (good normal grow environment) it will still collapse.
Only when your roots have developed seriously (bottom of the straw is fully open) do you want to have your plant in ideal conditions. Then your plant is able to uptake as much moisture as it's losing through the leaves.
What it looks like has happened is your transition was too quick. You need to slowly go from very humid and cool to normal conditions with clones.
Your leaves are clawing because the plant is losing moisture faster than it can absorb it and not from lack of moisture in the soil, but the lack of ability to drink.
Up your humidity, they probably don't need the dome, but definitely more humid than where they are now.
Don't water or feed if the medium stays moist, you want the roots damp, but not soaking, but your main concern is humidity.
Also in this case I would advise against cutting dying leaves off. It's your plant's fat reserve and it's eating them to stay alive, the more you take off, the less it has to draw from and the faster your plant will die if you don't fix the problem, so you're just giving yourself less of a window to recover in.
