First layer has 'spots', but the print is amazing, and the bottom looks great too

My first layer of a print does these weird spots in some areas.  The bottom of the print looks great, but Id like to get this fixed up.  Z calibration looks awesome in the same spot, so thats whats confusing me.

Second layer covers this and everything is awesome from there on out.  So Im at a bit of a loss. Anyone?

Best Answer by JoanTabb:

looks like LiveZ is a little low.
the rippling, is filament being pushed out of the way by new filament. 

you need a smaller negative number for live Z

Waves are a tell tale sign of live z being too low. If it's only on one side, left or right, it could indicate a tilted print bed. Google for Prusa mini xz skew.
