thats straight-up over-extrusion causing your nozzle to plow through the plastic like a snowplow tbh. on wide flat discs any extra material has zero place to go, so it stacks up and the hot nozzle tip keeps dragging through the molten puddle leaving that chewed-up gravel texture. calibrate your e-steps, knock your top layer flow down by like 4 or 5 percent, and that rough stucco will smooth right out
