I recently decided to try Paterson FX-50. I developed roll of Ilford HP5+\nexposed at 250 and it turned out grossly underdeveloped, extremely thin and\nwith very low contrast (unprintable with a condenser enlarger). I followed the\nenclosed instructions faithfully and used distilled water. I noticed that\nSolution A had a very slight yellow tint. Is that normal? Should Solution A be\nas clear as B? The instructions indicate that a "yellow tint" indicates that\nsolution A has oxidized.\nBoth bottles had just been opened and were bought a week before. They were\nstored in a cool basement at around 55-60 degrees.\n\nThank you in advance for your help.
