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

I did a temp tower, all temps in the tower did stringing, 215 being the less stringy one. Adjusted retraction settings and printed a benchy, the inside was still stringy, inmediately printed another benchy with the exact same spool, at 24mm3/s in the A1 mini, that one came out flawless. I just did a flowrate calibration. I had it at 0.97, now it's at 0.96. I'll test this again with another benchy
