You didn't say what materials you are using, but I would guess
T-Max 400, heh, heh. If so, try Tri-X at 400 in D-76 or Tri-X
at 800 in Acufine - and don't cheat on the metering. This should
solve your problem unless there is something wrong with your meter
or shutter speeds. Other possibilities: lenses used wide-open are usually slower than rating; if the low light is tungsten, meters
usually meter the orange color of the light incorrectly - you may
need to use 1/2 to 2/3 stop lower film speed rating under these conditions.
Hope this helps.
