just curious
Ok so I developed five rolls in my Jobo lastnight and all five of them appear to have this ugly brown "trench" -is the best way I can put it- right down the middle of the roll. There is the appearance of some kind of halo's around the sprocket holes on all of the films also.
I use 5L bottles for my solutions, and then I have 1L bottles which I use for day to day developing and I generally dont measure out exactly how much I put in the tank -safe to say that I always throw in about 700-750ml of solution into my tank (its a Jobo 2551 five reel tank), and I generally use that 1L solution twice and rarely three times before I take from my 5L stock bottle.
Ok so two things about lastnights dev session; Id used 650ml out of 1000ml the previous night on another dev excursion (basically if I use it twice then there is 350ml of unused solution which gets added to the just used solution and I see that as a kind of replenishment), lastnights dev I did for 7 minutes (the film was Tri-X, and it was 20c), and I for the first time actually measured out the developer solution according to the intstructions on the 2551 tank which says 640ml (so I was over my 10ml BFD..) -my thoughts are that this amount is in fact not enough...
The second thing is that this bag of XTol is in fact just and I mean two weeks, out of date. Remember that I developed five rolls the night previously with no issues. My friend believes that even though there is that 350ml cross-over of unused developer in the 1L bottle, the XTol's post-dated-ness', isnt enough to counter the possibility of its possible exhaustion.....
Opinions & possible repair possibilities Please.
Thank you.

Why don't you try one more time with a single roll, this time correcting for all variables you think was the cause, and report back if you still have a problem. If not, problem solved.
It's much more useful, and helpful in diagnosising the problem if you give it one more try, make sure all things are correct (fresh solutions, camera you know works right, proper temps, etc.) and if the issue repeats itself then you can better focus on what might be the problem. I'd bet 99% of the time the problem goes away and you're done.
Otherwise everyone is usually just guessing at what might have been the problem and what's the point in that?

You might not have fixed sufficiently, how old was the fixer, it has limited self life when opened. The stain may clear in fresh fix, easy to try?

But exhausted fixer would have been all over not a "trench" down the middle with halo-ed sprockets....
