Hey everyone - Very new to this forum and new to bonsai in general so looking for some help. I have a Green Leaf Japanese Maple I picked up at home depot early summer when they had some big sales, and got it for a great price. Since it was sitting in the parking lot, there was lots of leaf scorch and once I repotted I also trimmed the tree down quite a bit and defoliated. I now know this was probably a bit too much to do all at once, but the tree has done well and pushed out a ton of new growth. From here I want to let it grow out a bit before doing anything else, and I will post a question on styling plans later on.
For now, my main concern is a bunch of black spots on the top half of the trunk/main branches and am having a hard time diagnosing. Please see attached pictures, and if anyone can add some color here it would be greatly appreciated!
