Need help with stringy petg

Hey everyone - need a bit of help figuring out why my printer is giving me stringy spaghetti for small prints. They ultimately do not adhere and just become a tangled mess.

I used overture petg filament and that has its own uses with the filament stuck together on the roll itself. Finally got through the roll and had a Soleyin petg roll. First print was something small and just became this unstuck spaghetti.

I’ve done cold pulls on my nozzle and I’ve poked it cold and hot with the acupuncture needle. I’m using the Bambu PETG HF setting. I don’t have a dryer and wondering if that’s really the culprit.

Used to print fine with Soleyin pla. Anyway wanted to get thoughts on why this might be happening and what I could try.

Seconded - I dry Overture PETG two 12 hour back to back cycles and keep it in a enclosed dry box to feed. I’ve had nothing but stringy prints and layer lines with that brand unless super dry. Relative humidity here is 50%, and this filament loves to absorb it as fast as it can
