Bottoms of prints come out rough


Not sure how to describe this…the bottom of my prints are rough. This particular one I’m the pics, the roughess goes up to half centimeter? It’s on the outside and inside. I printed at 0.12mm, PLA+ 215C needle and 60C bed temps. Happened to every print. I printed a LEGO block and it was like this at the bottom for maybe 1-3 mm.

Any advice appreciated! Also would be nice to know what this is called…the roughness.
