All your processing technique seems to be ok except I would do a 20- 30 sec rinse of clean water between the stop bath and fixer. Also advise checking time on the Ilford fixer that you are using . Paper I usually fix for 2-3 minutes and film around ten minutes. Also check that the fixer is the one with a hardener built in. The one without hardener is usually for paper.
You also mention about the light switch indicator this is a potential area for fogging as most b and w films are panchromatic and are sensetive to wide bandwith of light wavelength.
GOLDEN RULE 1--- THE FILM SHOULD BE LOADED INTO THE TANK IN PITCH
BLACKNESS.
GOLDEN RULE 2---BUY A DARKROOM CHANGING BAG.
Don,t worry about the comments relating to sharpness lets get the development side done first.
Keep shooting.
