Trouble shooting c41 dev issue. Green specks showing up on scans, dark spots on negatives.

[darkroomdweller]

My processing set up is a jobo cpp2 with lift. i processed several tanks mostly containing portra 800. Chems were dumped/swapped accordingly, using cinestill chemistry. Almost every roll had these weird green specs on it. I cleaned inside the lift the best i could, Switched to kodak chemistry with seperate bleach and fix, and then did a tank of 6 rolls to see if the issue still came up. All rolls good with the exception of portra 800 (120) which still had the spots. Its on the negatives as well as scans so its not something with the scanner. Its not dust because its green and kind of glows. I am so confused. I've processed thousands of rolls of film and never had this happen before. Wondering if anybody has seen it and has leads on how to fix it? I've hit a dead end with trouble shooting. At this point the only thing i can think to do is replace my jobo reels and tanks as im wondering if this is the result of years of use on the equipment creating cracks etc for particles to settle in that are then getting released during processing. I would deeply appreciate any help/leads to help solve this. Scanned with Noritsu HS1800

Welcome aboard @darkroomdweller !
That's a frustrating issue you've got there and I also don't recognize it off the bat. My first guess would be that this is due to contamination of the lift mechanism of the Jobo. I'd be inclined to forego the lift for a while and just dump & fill manually instead, then see if the problem persists.

Did you do a pre-rinse in the sessions with the affected film?

Glowing would suggest a light source. I know not very helpful.
I have never seen contamination so sharply defined.

Can you show a backlit image of the negatives?

I did a 2 minute pre-soak

I'm asking because I wonder whether the pre-rinse water might have been contaminated. A pre-rinse can work fine, but be sure to take measures to avoid any possible contamination as the film is evidently exceedingly sensitive to any chemical disturbance at this stage.

This is strange. I have seen many similar defects, but they were caused by a particular type of fungus (or bacteria) affecting film that was slightly past its expiration date and stored in a humid place. When examining a piece of unprocessed film, the defects in question are clearly visible in the light - it appears that the biological contaminants "eat away" at the emulsion, causing blue (violet) and green circular areas with reduced density...
