I've read in several places that using back off speeds and clean nozzles can help. I'm running with a new nozzle. Travel speed 150, retraction speed of 20, print speed 50. I think some of these are just defaults with cura 5.4 but I get the same thing with a higher retraction speed. What else should I look at?

Yeah mate thats super usefull 1st print for every new filament. Temp tower, flow tower, retraction tower and you are set.
Btw calibrating retraction is not just changing speed, you need to find speed and distance. But yeah like others said, your petg probably needs to be dried first
