Print quality issue - AMS related?

Hello all, first post here. About 450 hours in on the h2c and loving it for how easy it is to use (coming from 2 creality I gave away when I bought the p2s, now h2c)

this week I’ve been getting some weird artifacts from my h2c. It’s mainly seen in the pink and the white, but also can be seen in the purple tail. Highland cows in the background are fine, it just started doing it the last couple prints. And of course the last print is the pink benchy that came out great. Extrusion issue for a given nozzle? Everything but the dark purple is loaded in the AMS 2 pros I have on the right nozzles (AMS ht on the left). Both prints stopped so the tops are missing. Idk.
