I'm thinking you're fine. Leaves get holes in them from damage when they're young. I see you're using the stiff bonsai wire next to the young leaves. That wire can be tricky to deal with. I'll bet you a gram you damaged the leaves when training. I'll bet you two grams you've already done it again and won't know until the leaves grow. Leaves can also get the crinkly edges. If you don't see any bugs, it's just a thing.
