Thank you everyone for your comments. I do use an acid stop bath and I use the Kodak Rapid Fixer. I use the prescribed speeds for each style of film on the JOBO, sheet film has one and roll film has another speed. I use the JOBO drums that are designed for sheet film and of course the emulsion side is facing the inside for developer contact. Has anyone tried Illford DDX developer? Someone told me its better then T-Max. Otherwise I will "Re-do" my film, time combinations to get a longer development time.
