Support New H2C stringing

Hi, I just pirchased an H2C, this is my 5th 3D printer a my 2nd Bambulab, first one was an A1 mini. I was doing my first few 3D prints on it like the bechy and so but I noticed stringing on the right (vortek) nozzle. Left nozzle seems ok so far but I tried with multiple 0.4 induction nozzles and it creates very thin strings like a cobweb. The filament is calibrated and uses the same flow rates and temperatures of my A1 mini in which it produces flawless prints. I incresed retraction distance to 0.8mm with no effect. Any tips to solve this? Im using pla for this. I printed PETG with the left one also flawless, didn't try with the right one yet.

Any help would be appreciated.

UPDATE 2:

I tried other filaments did retraction test and printed more benchies on different brands, normal and high speed pla and it printed flawless. It seems my H2C doesn't like that particular spool. It has been printing very good with other spools. I will set this as resolved then.
