help. i'm getting dark swirls on my prints out of the developer. i notice them as soon as i can turn the light on to see them in the fix. i'm using dektol with clayton odorless fix, no stop bath. i wasn't getting them at first but now am. could i be that i didn't scrub the bottom of the developer tray the last couple times? even though they're being processed image up? if so should i scrub the bottom of the fix tray too? the swirls are long and look as stripy. they look like water lines.
