Do you know how to do a clip test?
I developed another roll of Delta 400 this weekend and fixed it for 5 minutes. The negatives did not have the brown tint. I haven't done the clip test yet but I will from now on before I develop a roll. With this last roll I added about 40ml of fixer to the leftover solution and made sure to mix it completely.
