Need a better picture. Might be leaf miners or some kind of bug. Is it shiny? Are there tiny black dots near the damage? Is that the only plant with that damage? If the black dots are there it is leaf miners.

Leaf miner of some type (there are several). At this young stage I would not hesitate to spray w/liquid sevin. Make sure you soak the undersides of the leaves, that's where the bastards hang out. Easy fix.
The bastards hang out in the leaf. That's why they are called miners, or sometimes borers. If you determine that's what you have, remove the leaves most affected and treat the soil to kill the larvae and hopefully interrupt the cycle. Can be tough to control.
