Are you using the same fixer you used before? Perhaps it is near exhaustion.I have now tried re-fixing in fresh solution and the markings are still there.

It might also be dichroic fog.
Then I lean toward dichroic fog, which I have rarely seen.I dumped the old batch and used fresh new stock Tetenal Superfix Plus diluted 1+4.

Were you using replenished X-Tol?
It does.I was using T-Max developer as I had a time listed for the SFX film. Thinking about it, the Kodak developer does warn about dichroic fog, but I thought that this applied towards sheet film.
It does.
I do note though that Ilford's data sheet does provide a developing time for T-Max developer.
I have a vague recollection of reading that the 120 SFX is, unusually, on the same film base as the sheet film, but I can't find any confirmation of that, so my memory may be wrong.
Tom, the fixer had gone almost neutral or alkali and was near exhaustion Dichroic fog is a strong possibility, sometimes quite strong fixer will clear it but too long will act as a reducer. I used to see it occasionally but with experimental work, mostly with monobaths. Ron Mowrey (PE) said he'd seen it with Alkali fixers where a stop-bath wasn't used.
