Am I Doing To Much or To Little & Damage Leaves (Pictures)

First time grower here. Trying my best to do everything right. If you see anything in these pictures I’m doing wrong, or something I need to add, please, any advice would be grateful. Also, a couple of leaves got damaged. An object fell on them. Should I remove them or just let them be?

You can leave them. As long as they’re green, they’re useful.


Thank you.
