That is what's causing all the sooty mould (black powdery crap on the branches) You need to treat that with an oil. (branches not leaves!) At this stage, painting is probably best.

You have mites or some other sucking pest on the leaves. Perhaps thrips. This causes the fine spotting and pitting. You need to find out exactly what with a glass so you can treat it properly.

The distorted growth with the black tips. This can be caused be a fungal infection such as leaf curl or some kind of blight but the fact that it is on your Maple as well leaves me suspicious that it might be root trouble. I think your mix for the Haw is way too course. They like finer tighter mix. That's just a side issue though. The big problem is placing a root ball surrounded by a fine mix into a coarse mix. That can rot roots in a week in some cases. I don't know if that is what you've done???
It is far better to completely bare root the tree before changing soil texture.
