I am new to analogue development and just started using the Fomapan P and Excel developers. When I mixed the Excel developer, even after the solution was made to a working solution there was a bit of residue left. The residiue was orange looking particles - possibly about 5-10g in total.
I wonder if there is a precedent to this - is it something that is normal to the mixing of the solution?
