    Jobo 3005 8x10 streaks on negative

    I have been testing my new Jobo 3005 tank and my first development ended with streaks on the negatives. I have some ideas why but before I test again I want to check with you all to get some tips.

    Tank: Jobo 3005
    Film: 5 sheets of 8x10 HP5+
    Developer: 1000ml ADOX XT-3 (XTOL) 1:1 @ 9min
    Rotation: Manual
    Pre-soak: Yes, 1 wash maybe 3-4min. Filled the tank max
    Pour developer: Put the tank in 45 degree angle, and poured slowly (the tank cannot be filled quickly) without rotating the tank during filling. Filling took 15-20s due to me not being used to it. I put it on the manual rotation and started development.
    Rotation: Constant. Switched direction every 1,5-2 rotations.

    My previous method was using SP-8x10 tank and never had this problem. With that I had tried both with and without pre-was and never could tell any difference.

    Clear streaks in sky in top left, but if contrast is manipulated you see them in the rest of the picture too.
