It's nothing that I would be concerned about :-) A couple of holes in leaves is minor, but keep an eye on it in case it proliferates, then you may need to search out the culprit and destroy. But it is just as likely that what caused the holes has moved on. Some of the new growth is slightly deformed but there can be various reasons for that and I'd suspect that some stress as those buds developed is the source. Again, nothing serious to be worried about.

"I had to trim it back quite a bit as it had never been 'groomed'" - I'm not sure I understand this statement.........can you explain a bit further?

Thank you for reply.

When I got the tree it was very overgrown and had so many leaves that were burned. Once replanted I trimmed many branches and leaves which had both dieback and leaves that had the white powder mold/mildew. The tree had no air circulating through it so had to cut back inside branches.

Its growing many new leaves and I take it as a good sign of the tree trying to survive.

This tree has no graft that is why I assumed its a Acer Palmatum (seedling). Is that a correct assumption?

If no graft then yes, it is a seedling Acer plamatum.
