#1 Is it possible that you messed up the dilution of the HC110 and got it too dilute? Also was your developer unusually cold?(posted 8983 days ago)#2 Sounds like your fixer is depleted. Get some hypo-check and see if there is too much silver in it. Or better yet mix fresh fixer. Then go back and refix the films you had problems with because if the fixer wasn't any good they weren't adequately fixed even though they cleared.
