Hey guys, got my printer about 2 weeks ago and have been getting great prints out of the Creality white PLA that came with the printer. The roll ran out yesterday so I went and got a new Grey Creality roll today and hooked it up. Got one print out perfectly but since then have had nothing but issues with different prints either not sticking in single points, leaving obious gaps between lines and being a bit globby sometimes. I've tried changing the temperature of both the nozzle and the bed to no avail and have relevelled a couple of times. I'm at a bit of a loss given its essentially the same filament, just more of it in a different colour. Any ideas would be greatly appreciated!

EDIT 2.0: Thankyou for all the help! I've got it printing much nicer now and really appreciate everyones recommendations! :)
