Is it appearing on any of the growth above or just the single leaves that first come out?

Looks like damage of some sort. Could be from the wire you have training it, or a bug. Small bugs usually dont take chunks out so my guess would be
a caterpillar, slug or snail if it was.
Inspect the underside of leaves,
Good luck Happy Growing

If the rest of the plant is healthy, I think it's caused by a bug. Remove the infected leaf and observe if it spreads.
