Hello GuysMaybe sombody can help me,i dont have normaly pests on my bonsai but now here is one .Is this a pest ore a disaise and wat to do with it??

Can't see anything on leaves, I don't think there is anything to worry about. Leaves do die, get damaged by wind or rain.

It just seems to be eaten... How's the whole plant looking? Where do you live?

I live in Belgium near the coast.Its seems to been eaten but can not see any eaters

Seems like fungal, or possible root trouble. How humid is it?

Last spring I had a weird similar case on my Trident Maple, new leaves getting it's tip dried and when the leaves grew up they got curly...

I even shared on the initial stage here on the forum, but after that it spreaded and got a bit worse.
But after sometime researching and asking around, I found out that it was fungal, (either Phoma or Anthracnose or even both).
I managed to treat aplying a good fungicide once a week.

Here you can see how bad it was getting.


About 2 months later growing healthy.

We had a very rainy winter like always,soil is 2 parts akadama 1 part bims 1 part Lava very good drainage ,do use this soil mix on all my acers for years and this is the only one with problems
When repotted last year no root rot.
Will lift him out the pot and look ad the roots if sommething is wrong.then i am shure its not root rot
Thanks anyway for the tips
