What is happening to my deshojo? Trunk cracking, fungus?

[Noulinator]

Hi,
One of my smaller deshojo materials suddenly seems to be acting weird. The trunk has gotten somewhat discoloured and the bark is suddenly cracking. I see black/dark spots with or without white dots on the tree.
Foliage looks healthy and just fine.

Tree was repotted before bud break. I havent done any pruning this year. Last year the tree was doing just fine.

Any ideas?
I have been fertilizing it a bit heavy with biogold in teabags with spagnum moss for moisture.

I just moved it away from my other trees. Hope it isnt something too serious that could infect my other trees.
Here is also a video:

I'm not 100% sure what the issue is but it seems like part of it has died off and perhaps the tree has continued to grow and the cracks are just that new growth pushing off the dead part.

I'm also quite concerned about the black areas especially the picture with the white spots. That looks like Pseudomonas syringae.

I removed the fertilizer just to be sure it isnt stressing the tree unneccessarily.

Hope it isnt too serious. Will wait and see what other people think it may be. My thoughts was on pseudomonas too.
