What have your first layers looked like before this? The hard to remove skirt on prior prints is usually from your nozel being too close to your bed.
Before this they were typically ok - I did tram the bed again using a sticky note just to be safe. However, since I'm new, i'm still getting a feel (literally) for how much resistance is correct. Would a print sticking too much to the bed be an indication my z offset is too low (meaning nozzle too close) ? Typically people complain about too little adhesion, and i have too much lol
Yes, leveling too low can give you very strong adhesion. It's worth noting that PEI beds tend to lose adhesion as they and the print cool down. I can remove cooled prints without much effort off my bed, bit hot prints take some more convincing.
You can set nozzle distance with a mechanical feeler, like your sticky note, but you will need to fine tune some based on things like extrusion temperature and type of filament. This guide was made for printers with auto bed leveling, but the pictures are helpful.
Here are some signs you're too close to the bed:
That sounds exactly like my problem, I will adjust, thank you very much
Beware that this may convert you into a, "huh, nothing is sticking that well" person. In that case, clean your bed first.
First layer quality is probably the first thing to get right since everything else is literally built on top of it.
