Wall defects. Only on certain areas, other areas are perfect

what can be causing these defects on the walls? Clogged nozzle?

The model was perfectly attached to the bed

Prusament PLA, dried and printing off dryer

Using Prusament PLA profile that I used before with no issues

It is not FUZZY skin, other sides of the model are perfect.

Can you attach a zipped 3MF? Without looking at slicer settings it's hard to tell. What kind of nozzle are you using? Do you have it correctly setup? This looks similar to when you slice for a HF nozzle and only have a regular flow nozzle mounted. Otherwise, try lowering the volumetric flow. Or check cooling fan speeds. 

Anyway, hard to tell without looking at the project file.

yeah it is weird. I was thinking the nozzle was clogged maybe? Mostly because this is prusament pla with a prusament profile, so it should be pretty close to perfect from a profile point of view. 

I just replaced the nozzle to see how it goes, if it does the same then I know it is something else.

Try printing then with the door open. It could be heat creep clogging the nozzle. I rarely print PLA so hard to tell.

rmmmh, I dont think it is or it would otherwise continue throughout the print?

Ok seems like the issue was in fact, that the Balanced profile is too fast for Galaxy PLA. The profile needs to be slowed down 20%.
