VCore4 500 hybrid 2nd layer major over extrusion

I've been trying for a few days to print a bumbag and now have a solved my first layer issues enough to try the whole print. Shortly after the 2nd layer began, I'm getting this crazy over extrusion. A few blobs I can deal with but this is unusable. I can't decide if this is a Z issue, slicing, or flow calibration. I also don't know how to confirm if I have one of the faulty earlier release rapidos but that crossed my mind. Any suggestions would be appreciated.

Printing in PLA with the rapido 2 uhf .6 nozzle for now. Dried it yesterday for 5 hours in sunlu s4. (Petg later if I like my layout)

PID tuned the nozzle, did cold and hot meshes. Print was started after ~30 min preheat at 70c

210 nozzle, 65 bed. Did flow and PA tuning. Using 36mm/sec on flow, 1.012 was my extrusion multiplier.
Fan at 20% for first layer and I tried going up to 60% before I cancelled the print. Didn't notice any reduction in the blobs.
Max accels are 6k for Y, 15k for X.
Sliced in PS
