I was printing PLA, it looks ok up to a certain height (although it was warping slightly), but then it becomes ugly. I will do a test print of the same height, butaybe you already have an idea.

Looks like a clog, could be caused by too much retraction, too high temp combined with too low print speeds resulting with the filament being cooked inside the nozzle.
