That kind of damage is caused by a category of insect called a "leaf miner." They make those channels throughout the surface like they're playing that old Dig Dug video game. Remove the mined leaves because they probably have eggs sitting inside the leaf tissue, and spray with spinosad. Incorporate a multi strategy IPM for the rest of your grow because the leaf miners are liking that plant and they'll try and come back.

I wonder if you can just remove the leaves in lieu of spraying. I have only seen leaf miner damage on a few leaves that I just pulled off and didn’t see any damage again! They seem to be pretty rare around here! Haven’t even bothered to research what they look like!
