This appears to be under-extrusion and z height.
Stringing could be an issue of wet filament, or too high of a nozzle temp, or retraction settings. Since you're already 10 under the recommended temp, go back to whatever the median temp is. And I suspect then you're still under extruding. Once your e-steps/flow is correct then you can tune for z-height. Do not attempt to fix adhesion solely with z-height. Z-height is the last variable once you know e-steps and flow is correct. ESPECIALLY if you're attempting to print anything with reasonable geometric accuracy.
There are so many co-dependent variables in 3d printing. The right way to do it would be to calibrate all settings/configuration for every SPOOL. That's right not every brand or color, but each individual spool.
However, depending on your tolerance for finished product and your printers overall ability this may not be needed. I've managed to do well to calibrate once for a specific brand and color and from spool to spool things have held up well.

Minimally you should be doing the Extruder E-steps calibration, First layer, slicer flow, temp tune, and retraction tuning.
As for z-height, maybe you already have feeler gauges for doing spark plug work? A proper feeler gauge is a tremendous help. Your Z-height should be lower/smaller than whatever your initial layer height is. Which is a custom variable based on your needs for a particular print. For example. In Cura I typically will use a .4 nozzle with .16 layer height. Then my initial layer height is .25 with a 120% flow rate for the first layer. I also bump the temp about 5-10 over whatever I've found my ideal print temp to be for that specific filament.
