Maybe coat a sheet of paper and leave it in your darkroom in total darkness for a couple of days on a counter where you work. See if something is settling on it?
It could even be clothes that you wear…. so if I were in my metal shop and grinding tool steel, then went to make a print…I would have a print that looks like I spilled pepper on it.

I m starting at square one again and beginning the process of systematic elimination once more. I am fairly certain it is metal contamination early in the printing process, just can t seem to eliminate it no matter what I do. I m going to try new FO and mix my own this time - that s about the only thing so haven t done. After that, I m wondering how to check for metal particulates in the environment, beyond the obvious rusty pipes/hinges etc.
