I'm about to run another test with a change of process...taking the film from the developer straight to a stop tank with only a couple of seconds exposure to the air.
This is exactly the problem that I had, with mottled development.

The Pyrocat mixed first as green, and it would turn color after a little while to almost black. I bought a new kit and it mixed green again. But it didn't help my developing problems any. I tried distilled water, which also didn't help. I can't even remember all that I tried anymore. Sorry I'm not of more help.

It could be that one of your solutions are contaminated, or it could be that you're not using enough agitation. I never solved this problem.
