Could be a clogged nozzle like you said, I’d check your extrusion gears too in case they’re slipping. I think it’s worth mentioning, in my experience I’ve noticed different brands and even colors have different flow rates. Which means to every roll needs to be calibrated (yes it’s annoying). The process gets really tedious and I haven’t even done it for all my materials, but it really makes a big difference in durability and print reliability.

I double checked flow rate right before the print and it was extruding the proper amount. The print started out decent and then just turned to shit once it got to that point. I’m gonna pull the whole hot end apart tonight and clean it and re assemble it, slice with orca and see what happens

I’d make sure your z rods are clean, and look around your extruder for filament around the gears, make sure those aren’t worn either. If your filament is going in at an angle it can start rubbing on the extruder shaving off your filament effecting flow and diameter of the filament.
