I do watch my enclosure temp and if it's below 70f it nothing sticks.
Most days I stick a small space heater in font of the printer for a few minutes to get things up to temp.
Also a partial nozzel clog can create problems.
Try heating up with loading filament after it starts extruding go to unloading pull the filament out and reload the filament.
I find this can help on minor clogs.
Your sure the other nozzle not dragging into the print?
