Hi all, Using Tetenal C-41, and the last two rolls I developed together (in a Jobo CPE2) came out with a green cast to them. I've attached a picture - the strip of negatives above is from a previous different roll development with the kit, the strip of negatives on the bottom is from one of the rolls in question. Temperature control was tight, over the 3:45 minutes of dev the temperature hardly deviated. However, this was roll 10, is this sort of result indicative of exhausted developer? I've searched but didn't find anything conclusive.
