Some negatives developed at different photo labs scans ok.
I only have an BW Enlarger and cannot try prints myself. So I only scan.
My explanation is that the first two dye layers on the negative are overdeveloped,
and the third, the cyan dye layer has an low density and is underdeveloped but I dont know if I am right.
I tried to rise the ph up to 11,5. It seems to be the wrong way.
Maybe I dont understand and my thoughts are completely wrong?

First, given you have one lab that works and one doesn't, talk to your labs, it may simply be that one cares and one doesn't. They should also be able to tell you if your negatives are over exposed or under exposed.
Second, with regard to scanning questions and all that digital color balancing jazz, APUG isn't really the best source, in fact it's off topic. http://www.photoshopuser.com may be a better place to ask. Lynda.com has tutorials on scanning too.

If the scan is too magenta, the film is too green. This can come from a variety of effects including fog, improper development and a host of other things. Since I have no idea what your workflow is, I cannot judge but if it is truly magenta then the problem is in the yellow and cyan layers or in the magenta layer.
Is the entire film greenish? Or, is just the image area greenish? Or, is there no cast to the negative in any way, but it scans magenta? This might help evaluate the problem.
As you remember I just try some experiments on developing.
1. Yes the negatives are greenish in the image area and the perforation area at the edge is greenish too. On negatives that brings better result the perforation area looks more orange.
2. I try to keep an development at 25 C with one agitation every 30sec at 21min.
3. Can the PH be the problem, it is at 11,5 should I lower it?
4. I tried Fuji Hunt Chemistry and some own variations. The only effects seems to be on the saturation, sharpness and developing time, but all have more ore less the magenta cast on the scans. (I cut an film into small pieces to be able to compare the results)
5. Adding some Sodium Carbonate to the developer seems to help a little. Can this be?
6. Maybe the Starter (Bromide) is to much or too low?
7. It would be great if I not only can get normal negatives but the opposite slight yellowish images.
is this possible?
(All my films are from the same batch that brings normal results developed at pro labs. Also I tried some other brands, the same)
