I'm guessing you mean 215 C; 215 F would be way too low.
I'd say your bed temperature is too high for PLA, too, but that's not going to cause this problem. Speed is fine, too, assuming you're satisfied with the print quality.
Few thoughts...
It's probably not the filament. It's almost never the filament.
Are you sure it's PLA? It's not something else (ABS, ASA, PETG, TPU, "soft PLA") that was picked up by mistake, or shipped in the wrong box? The 'grippy texture' sounds odd. (what do you mean by "grippy"?)
Did you measure the filament? Is it within spec, and have you calibrated your extrusion multiplier?
Have you tried increasing your nozzle temperature? Try printing at 215/220/225/230 and seeing if it flows better.
Is the extruder motor skipping? You should hear a clicking sound if it can't feed the filament. If it's not clicking, it's probably not backing up in the printer, which means it's probably feeding fine.
Have you tried cleaning the nozzle to make sure there are no blockages? Try doing a cold pull to make sure it comes out cleanly.
Have you calibrated your bed level? Your print lines look pretty round, and I'm seeing several strands that seem to have shifted around on the bed, which suggests your nozzle is too far from the print bed. You need this to be as close to perfect as possible - if the printer thinks it's printing a .2mm layer but it's actually .25 or .3mm from the bed, you will have problems.
With a properly calibrated bed level/nozzle height, you shouldn't actually need glue on the bed. PLA will stick fine on a 50 - 60`C glass bed. If you're having problems on a 70`C glass bed to the extent that you need glue, again, that suggests your nozzle is too far from the bed.
