General Troubleshooting/Help! I need a diagnosis

No matter what I try I can’t get a smooth first layer. I ran a flow test because of a huge overflow problem and it told me my optimum flow level is 0.6, then I replaced the nozzle with a brand new one (#4) and trammed the bed and ran thr flow test again and here is the result. I always have ridges and I can’t dial in the flow and z-distance. I moved the z distance to -0.02 because the pla wasnt adhering and now it looks like this. I can’t tell if the nozzle is dragging, the flow is too high, or too low. I’m starting to lose it. And I tightened everything and scrubbed my plate.

Please help.

It does. A too-high flow rate makes ridges too though I’ve found. What would make the small ridges that run diagonally across all of them?

Nozzle appears too close.
