is it ok to use miracle gro all purpose plant food?You are supposed to keep rockwool wet, it works very well for cloning when saturated.
I suggest you use nutrient solution instead of water now and then wait 2-3 days.
The light might fry them, and only change one variable at a time.
Always check the pH of your nute solution or water.
Mist only with water, btw. Foliar feeding is tricky.
