Aluminum foil will cause the light to bounce back and burn the underside of the leaf. Use something black.

With a cube that large you need to let it dry before you refill. You need to time that and set it accordingly. When you have a good root structure poking through you need to move the schedule back up a little so those don't dry out. The problem is the rockwool will stay moist. Just look for mold too make sure you have air moving around 24/7
