Pic 1, spots, bugs is my first thought, are you spraying anything on them? (with the lights on)
Pic 2, the tear is wind damage
Pic 3, Leaf curls can mean several things from over water to bugs. Tip use the Plant Problems link above and look up leaf curl
Pic 4, very obviously an eaten leaf, 100% on bugs.
Pic 5, and all pics with leaf curl, can mean several things from over water to bugs.
Inspect them closely with at least a 30x zoom so you can see the little basturds, look at the under side of the leaves.
