Check your clearing time for the fixer, as that fixing time is quite short for the T-Max films.

And that does seem like a very short wash if you aren't using a wash aid - although TF-4 apparently helps with that.

I'm pretty sure TF-4 recommends 4 minutes for traditional films and 1.5x that, or 6 minutes for tmax-type films (Tmax, Delta, Acros).
