What's causing this pattern on my first layer? (sh.itjust.works)

I'm printing with PLA on a "PEO" print bed (really a textured PEI), on my heavily modified ender 3, and there's a pattern on the bottom of my first layer that I'm trying to get rid of. The top of the first layer looks fine, and changing the z offset in either direction doesn't help. I've also tried slowing down the print speed because I thought the extruder might be skipping, but I'm still seeing it at 10mm/s. Any idea what could be causing it, and how to get rid of it?

Edit: the first layer went down from the bottom left to the top right, but the pattern I'm seeing is perpendicular to the extruder path

This looks kinda like ABL compensation I usually run bed visualizer when I see patterns like this

My bl-touch mount broke so I've been doing manual bed leveling for a while. I just finished printing a 185x185mm part (half of a dactyl keyboard) and the first layer looked great from the top.

Edit: I also deleted the old bed mesh from my klipper config when the bl-touch broke
