i cant really give you more info about the developing prozess cause what i stated is all i do. here a negative that shows the streak.
Please consider the possibility that your squeegee may be causing the streak. There is a great divide as to whether a squeegee is nescessary and for years I was in denial ! There can be 3 ways a squeege can cause damage. Firstly direct physical damage of the wet emulsion by over enthusiastic use. Not so here. Secondly deposition of degrading rubber as a visible black line. Unlikely here. Thirdly, and more probable, a physical nick or defect in the rubber blade that leaves a wet trail of the final wash. Any minerals in the water can leave a subtle drying mark as a long tramline of differential density. Barely visible on the negative, this shows up on scanning or printing. What have you got to lose ? Follow your usual steps on a test film and instead of squeegeeing, final rinse in Photoflow and then with the film still in spiral, shake the water off vigorously and hang up to dry.
Kind regards, John.

I'd be looking closely at your shutter. It's possible there's something dragging behind, or in front of the curtains causing the slight underexposure. It's not a light leak, that would result in a lighter line in the photo (darker on neg)

Its a Leica. Horizontal travelling shutter. And I believe it has been inspected and cleaned.

I think some elimination is in order to narrow down the options.
Does this also occur with other film apart from this particular tri-x batch?
Does the same film exposed in a different camera exhibit the same problem?
If you look at the fully exposed leader of the film, are there signs of the same longitudinal band?

Do not use a drop of PhotoFlo! Follow the directions and then modify if and only if necessary.

Squeegees are a big no-no on film. They are good for removing excess water from prints and cleaning windows.

Do you have another camera you could try? Keep everything else the same, and see if the streak is still there on the film. Another option is to shoot the same scene at different shutter speeds and see if there is any change in the band. Also, does the band extend beyond the frame of each shot?

The streak looks well defined, so I'd suspect it's something to do with the camera rather than the film or development process.
