Under extrusion first layer new A1 printer

Flow 1.25 K 1.35 Always in the same spot. 80% of the print is flawless. I’ll have a hardened steel nozzle and a smooth print bed to test tomorrow. It’s strange because the flow dynamics are fine for 80% of the print. But why in this one area is it bad. The ABL not correcting for a dip in the bed? ABL should be able to correct! Also, why in the same areas? The tubes are not kinking or anything.
