PETG Temperature Tower leaving bumps on surface

So when printing that tower I encountered some weird pattern. But tbh I have no clue what causes them. Anyone got a clue?

I am printing Nunus PETG at 230°C.
I use 1mm retraction at 100 mm/s.
Printer is stock MK 2S.

If more settings are required let me know but maybe you guys recognize such pattern?
In the picture I show two different issues I encountered.

I find its hard to get a good surface finish with PTEG. Might be a property of the plastic and not machine settings
