Is the 4.9km of filament enough for brass 0.4 nozzle?

Hi

Since few day i can observe on MINI+ printer some stringing which affects the quality of prints. So my first try was to check the filament, so i did the cross check on the second printer and there was 'normal' without the issue. Then i tried fresh new spool of filament still the same. I reopened the extruder if something is wrong with it, all good and clean, anyway i did doubre check in the following day to confirm. I checked if i have skew plate, but anyway geometry is not affected. so i did the cold pull, but it's clear' i repeat, and also used cleaning filament just in case. I checked the ptfe tube in the hotend part, it's clean, not deformed. So at this moment i don't have more experience to narrow down the issue. Only thing i spotted is that extruded filament from nozzle has some little teeths every now and then, between one - two centimeters, more or less irregular pattern. I can feel the diffenece in shape in fingers. So in the end i concluded that maybe nozzle needs to be replaced?

It's three months old printer, and i printed some 4.9km/15kg PETG on it. So far no major issues with the printer.

Anyone has idea what else i have to check, in the manual it's written that nozzle should last houndredts of printing hours... mine i think has 1320h. And 90% of it is printing PETG.

thanks

if someone is interested how it looks like, to cut a bit the tip of nozzle...

already replaced with the new one on the left side, MINI is printing without issues so far, actually after 1st layer calibration now i'm printing some test cube, to conclude the fixing...
