Camden, I hear you saying two things here you might not have noticed; 1) poor Dmax and 2) brown coffee like stain?  Both can be due to bad ferric. Did you print with clean edges so there is a way to check for fog?


If your coating neither soaked into the paper, and got too little exposure, it could later get developed fall off the paper. Then the paper got subjected to a palladium rich, ferrous oxalate laden solution, you may get that type of stain.


Have you run a ferrous test on your ferric oxalate?

It looks almost as if it spent some time soaking in a tray of coffee.
