scraped leaves?????

Hey guys im growing 4 skunk#1 at the moment and they look ok.
This morning I noticed that a couple of the leaves look like bits of the top layer have been scraped off.
I cant see any evidence of bugs and was just wondering if anyone had any ideas as to what this could be?
Thanks

Would have to see pics for real to be able to help. Sorry

Sounds like light bleach. How close are your lights to your plants?
