"Strange" color casts on recently developed negs

So I recently started developing my own color film and Ive noticed a few things that seem odd, but I cant quite figure out if they are real problems or not. The first Is the color of the negative backing on the negs I developed myself. The film base itself seems to have a stronger red tint than any on the negatives I've gotten professionally developed. I've never seen a difference in the scans on 35mm film(i exclusively use kodak gold & ultramax in 35mm format), but when I recently tried to scan some medium format portra 160 and 400, I noticed that they had a noticeable blue hue to them before color correction. So far it has been easily corrected either in-software or in post. I am using epson scan on my V600 and it could just be the software, but to me it still seems a little off.

The second thing I noticed is a greenish cast to the emulsion side of the film when taking it off the reel after stabilizer. It always disappears once the film has dried, but I'm a little nervous about it because after a quick google search, A few sites indicated that it could potentially be improper fixing. Again though, I haven't noticed a difference in the scans compared to professionally developed negs.

So basically, is this cause for concern or am I freaking out over nothing? just fyi Im using the Cinestill "color simplified" C-41 kit, and developing it normally at the specified times in the sink with a fairly consistent 102 degree water bath, and using a tap water wash with the stabilizer at the end.

Please post photographs of the negatives, not scans so that we can better evaluate the problem.

-) 35mm films typically have no back-coating

-) the film base itself has no red colouring. The red hue is made up by coloured dye-couplers in the emulsion
(They loose that hue the moment they couple. The idea is to counter a typical color reproduction problem with those coloured coupler, yielding a uniform orange cast.)

A change of that orange hue in theory might be due to a different dyeing of the film base itself . Though I do not consioder that likely.

IMHO, if you want to get the bottom of whether you have a processing problem the first thing is to do what Sirius Glass has asked. We can take it from there.
