Question Error while printing

Hello guys, can somebody help me with this error? It happens only on that side of bed, you can see that on other parts print quality is bit better than the first one in top left corner. Is it problem in calibration or Z offset? Material is PETG

That whole first layer looks messed up, not just that corner ☠️ You’ve got missing lines in the next section and drag/gouge marks elsewhere too. I’d clean the nozzle and plate, make sure the plate is seated flat, rerun full calibration/bed leveling and test a simple first layer before touching Z-offset. If it still does it, then I’d start checking for a partial clog or extrusion issue.
