I bought my first and so far only mono RA4 kit, from Nova.

It's done well and I have made about 30-40 prints with it. Mixed up fresh solution today (I've had it two months) but the print comes out of the blix at the end with a completely copper/brown shade, even stain.

I believe this is the sign that the mono kit has gone kaputt?

The Blix and Dev aren't cloudy as such, and the bottom sludge when shook was not solidified.

I was just using my usual starting point of 55Y and 65M.

If it has, it's about time I got the Kodak RA4 Dev and Blix 5l kit anyway!
