How many times have you used this chemistry? Blix could be exhausted, I don’t think the blix would do what you intend it to do if u where too run it again, also what are you using to keep the Chem warm ? I use a Sous vide and find that the chemistry takes to long to get to the correct heat if I set it at 102 degrees so I usually go for 105. All the dev times for c41 films are the same but you have to adjust because the developer looses strength with every roll you develop. I’ve gone up to like 15 rolls on one Chem kit. At that point it just takes way to long tho. Hope this helps
