May be your nozzle is worned out. Try to increase the temperature by 5-10 °C.

PLA absorbs moisture. If it soaks up enough, it cooks out when you extrude it and makes a mess.

You can dry it out in an oven, but you need to be careful to let the oven get to temperature before you put the filament in.
