@oniongal what film is this?
My first thought would indeed be air bubbles.
Leaving a film in the soak for an hour isn't great; I understand what happened though. There's not all that much you could have done.
It's funny because I tried Finol years ago and used it for a while, and it never, ever went red upon mixing AFAIK. Chemically, Finol is similar to Pyrocat, so when I ran out, I switched to DIY mixing Pyrocat instead. But the Finol worked fine for me.
Maybe the Finol kit you received had been sitting on a shelf for a bit too long? I've had that happen with Moersch chemistry once or twice. It's stock that moves slow for many retailers, so you sometimes end up with old material. This shouldn't be the case if you order directly from Moersch, I'd expect.
black dots all around my film even on unexposed squares
To be sure, should I interpret this as follows: you see a colored (yellow/tan I assume) base stain all over the film, except in the areas that show up as black spots on the posted images? In that case it's a good indication that you were indeed running into an issue with air bells. An alternative explanation could be contamination of the film with little spots of something hydrophobic that repelled the developer.
Can you post some clear photos of the affected areas of a few negatives, preferably also parts of these unexposed areas that you also see visibly affected?
