Our “hot wings” maples made it through the winter and although they were behind the native trees in leafing out they seemed to be doing fine but in the last week I noticed this

It’s not chewing marks, and it’s not making holes all the way through the leaves
I couldn’t see any type of insects anywhere on the 5 trees

I’m going to go to the tree farm and show them my pictures but if any of you have any ideas please chime in
Thx
