Go into the dashboard and turn your speed factor down to 10-20%
Use the negative Z-Offset buttons (usually the -0.01) to bring the head closer to the bed

Small changes in the bed surface can cause defects. Just because the Z-Offset is good in one area does not mean it will work in another, despite the adaptive bed mesh probing that
This is what it looks like when too close or too far:
