What is causing this pattern in the first layer? (lemmy.world)

Flashforge creator pro 2 with PLA, standard quality preset, textured removable magnetic bed on the build plate.

The first lines are straight, but as it makes more parallel lines to build the layer, it starts to develop a scalloped pattern. This creates issues with smoothness when it fills back to join it from the other side later. I've leveled the build plate, although I suspect it's not perfectly flat and maybe slightly higher in the middle. Is this my problem? It appears to have the pattern even away from the middle if that makes sense.

This is my attempt at calibrating the first layer. I don't know if there's some other process I should be using (while I'm fairly technical, I'm new to 3D printing)

If you look around you can find some pretty good tests to characterize all the different features that contribute to good performance. Usually they include using a feeler gauge at several points, and printing certain test shapes in different areas. I don't have one at hand, since I'm on mobile. Can you describe how you leveled it already? If you're looking for something to try immediately, I'd try printing at 10 and 20% less flow in the first layer and see how it behaves. Based on that, you can adjust the offset if necessary.
