I'm Unable to get any PETG HF Filament to Stick on the Bed after having Switched from a 0.4mm to a 0.2mm Nozzle [Bambu P1S] (self.3dprinting)

So I got the 0.2mm Nozzle for my P1S to do some Detail Heavy stuff, while with PLA everything works perfectly Fine, Once I try to use any Roll of PETG HF it just refuses to Stick to the Plate!

I've been Mostly Testing on my Coolplate Supertack, but same issue happens on the Textured PEI. Both of them have no issues when trying PLA the Print before.

I've now tried a Range from 230c° to 250c° for the Nozzle and 60c° to 85c° for the Headbed with only limited result, as Only the Combination of 250c° and 85c° for the Heatbed got me the Brim around the Print to stick, but not the print itself.

What am I overlooking here? Is there some settings I need to adjust when switching Nozzles? Dp I need to go even Higher with the Temps? Maybe its the Flow Ratio? I've tried both the reset one and the one that was set with the 0.4 Nozzle with no real change. Cant run a new calibration for it since nothing sticks. Both spools of Filament have been dried for 48 Hours, with a few hours of resting before use ofcourse.

To note, PETG HF works perfectly fine on the 0.4 Nozzle and both Plates have been cleaned multiple times now... as seen to work with PLA. What settings work for you folks? Anyone with simular issues?

Have you tried increasing your first layer extrusion width? A wider first layer will squish the filament into the build plate more, which might help. I use a 140% first layer width.

Oooo I will try that now yes

That's how I solved my adhesion issues as well (with ASA and a .3 nozzle, but should be the same in principle).
