I used to mess with rockwool back in the day and if they were nice and wet when I put them on the dome and didn't open the dome the humidity was high enough inside they would not evaporate enough to need to ever be watered again or opened or touched or anything until roots showed up a week later. They don't have roots yet so they don't really use the water they get it from the humidity in the air and they need it constant to maintain turgor pressure.
As soon as you open that dome the temperature and humidity changes and the plants don't have the functions to adapt to that and they wilt. Any change in VPD at all is BAD. It has to stay so high so the stomata are basically closed.
I see a lot of my younger growing habits in what you're doing and I can really really relate. I was and still am a tinkerer. I know you're opening it too much to check and spray and love them up.
Try like I'm suggesting next time I'm not steering you wrong. I want to see you have the most beautiful healthy plants
