Don't rinse after develop. It can cause problems. I was happy developing develop->rinse->bleach at one place I lived at, my negs were great, so I never noticed problems. I moved states, and all my negs were terrible, I spent ages doing many test rolls, remixing each solution from scratch, until I decided to use a stop bath and inspect the develop negs out in the light after dev step, then found that after I did that and finished the process they were great.. it was my water rinse that was wrecking it.
