I thought I’d add that it looks like it’s overextruded. So much that the filament is being “pushed” out and curling back around the nozzle.

It could be the e steps, flow rate, etc but it could also be that your Z offset needs to be adjusted back away a smidge.

That could be part of the inconsistent print since the tool head movement over one section of the bed vs another may be affected by the layer below based on how the filament curled there.
