The EI50 rating of Fomapan only refers to the cut sheet film (4x5", 8x10" etc..). I have found that the roll version of this film is very sensitive to over exposure. Try exposing at box speed (ISO100), and cutting back agitation at the same time increasing dev time. I agitate for the first 30 seconds and only one inversion per minute. Dev time at 1+49 dilution @20degC would be 10.75 minutes (10'45"). This works VERY well for me. Much better grain structure than heavy agitation.
