First layer issues

I have been having issues with my first layer. Randomly started happening and seems to happen with every filament I try.

I have a Prusa MK3s+ and have been getting great prints with the occasional random deft but all in all I was happy.

One day I randomly started having severe bed adhesion issues and defects like this. Bed adhesion is no longer and issue but I still get these waves no matter what I do.

I’m speculating that it’s either the filament or possibly the nozzle. New filament and nozzle on their way.

The issues started happening one particularly extremely humid day so I’m maybe leaning towards too much moisture in the filament.

It also doesn’t seem to be the z offset since I am pretty good at dialing that in.
