Is it a single or double reel tank? Does it only happen to the top film in the tank- or the side of the film closest to the lid? The lines look very uniform. Any chance at all the lid has a very small light leak and the lines are the spiral from the reels?
I had some streaking issues with med format b+w film. The problem went away when I stopped the pre-soak.
