Strange outer skin print quality on Ender 3
My best guess is you have an under extrusion issue, possibly related to retraction: the issue is exacerbated on parts where the printer has to hop over a gap.

I would try running, in the order:


print a flow rate test, to ensure the amount of filament exiting the nozzle matches with your configuration
print a retraction test, to ensure you are not suffering from some bowden tube issues like bad coupling
check for any clog in the hot end, those can require a bigger pressure to build up before the filament start flowing again
print a temperature tower, to find out if 190° is the right temperature (seems a bit low to me)


With regards to point 2, the Ender 3 is somewhat renown for having poor quality couplers: watch the bowden tube couplers when printing and try to verify the tube is not moving back and forth when hopping over empty spaces...
