Check for a partial clog. 80% of the time i get that consistency with petg, its because the nozzle is partially clogged. The other 20% is the ptfe tubing is shot. Usually it partially melts and causes underextrusion.
Wet filament could be an issue too, but this is pretty extreme for wet filament.
You were right! All clogged up.
Replaced the nozzle, heat block (heating element, sensor, PTFE) and fan duct. Wasn’t able to unscrew the nozzle (got stuck 80% out) so I replaced the whole thing.
Did two new temp towers:
Left tower is 235 (top) to 260 (layers labeled 280-260 are all 260). Right is 220-240.

I definitely feel like 220 is the right temp for this.
Make sure you calibrate your e-steps after swapping hotends. I did the same thing on my ender 3 putting on a volcano hotend, and started getting overextrusion. After adjusting the e-steps it was back to normal.
