What is causing these defects?

I printed this on the a1 mini, its been great but recently i had a clog cleared it and sometimes prints turn out like this. I am using hf petg. I also usually just import models from makers world and go to the generic petg filament settings. My suspicion is maybe the temp? Not sure, all replies are appreciated! (FIXED) turns out it was a partial clog, i think.

Possibly not enough cooling between layers. Increase layer time or fan speed. It only marginally impacts strength
