That's a lot. I do get the occasional white spots but never that many or large.

I guess you clean all the equipment thoroughly with no residue and the spots are too large to be airborne from drying, I think.

That probably only leaves the chemicals or the water. Maybe your water has a lot of particles that stick to the soft emulsion during the wash?

Or maybe you should replace you chems in clean bottles?

Sorry, no answers, just guesses.
