0.2 nozzle Bambu filament issues

I printed a minature (dumbledore) with Bambu PLA basic light grey with a 0.4 nozzle without any issue. I got my 0.2 nozzle and now the same filement is giving Issues. Also tried the SUNLU META black filament and that works great with both nozzles.

Any idea why the bambu filament is giving issues? It looks like stringing and in some places the layers are loose. I am printing at 0.1 mm layer hight


WIth Sunla Meta and 0.2 nozzle same profile
