Looks like standard working solution small tank stuff. How much wash did you do between dev and bleach? I have a feeling there's nothing wrong with the bleach, but unfortunately I don't know of a good testing regimen for this type of bleach other than physical immersion of the negative in a tray and visually watching it while bleaching. However, I also could be wrong in that this particular bleach may not act the same way as a pot-ferri bleach at least with regards to visual inspection.
PE would know more than I here.
Stop worrying about grain, resolution, sharpness, and everything else that doesn't have a damn thing to do with substance.
