Bubbles in the negatives

My suggestion would be trying to use prewet with water, and probably trying to add a stop bath after developing. It could help with issues with uneven developing. I had a problem with streaks developing RA-4 in tubes, and prewetting the paper solved the problem for me.

I currently use a stop bath due to my SR-29 Bleach, but i will be trying a pre-wet soon, i think this will fix my issue.
developer dilution with time is a concern but i believe adjusting it with gravity tests to get it within spec might suffice.

@kyuut I agree the problem is undeniably there. I agree also with @Sanug and others that a pre-wet would be a good place to start.

I don't think developer dilution will be much of an issue if you replenish slightly above spec. I shake out the tank until almost no water drops come out. Maybe a couple ml of water remain in the tank at that point. My replenished developer didn't lose strength after 130+ rolls (25 dev cycles) of this.

i have seen bubbles like this in b/w film. if along just the edge it's because of too little developer. like those in your background, it was because the student who used the reel prior to the person getting bubbles did not thoroughly wash the reel after the photo-flo. the photo-flo was dried on the reel and when the developer was dumped it was especially foamy. don't know is this applies to color but it's plausible.
