The red print is the second layer of a PLA print I started, while the grey one is a PETG print that is exactly the same on its first layer. As you can see, massive improvement. The PLA I'm using is Qidi Rapido PLA, and has just been freshly dried. The build plate was also cleaned right before. What could be causing just PLA to have issues on my build plate? It used to work okay, but it gets worse every day. All my PLA filaments seem to have this issue, though my rapido ones seem to have it worst. The PLA works fine on the rest of the layers, its just the initial layer with the problem.

I'd usaully say wash your build plate with soap + water, rerun bed levelling mesh... (So do that) + Maybe also slow down the first layer for pla (20 - 30mm\s)
(Whether it helps or not idk, but lets stsrt there)

What temperatures on the pla?
