If it were mine regardless of the male flowers I would let it go until all the pistils have browned. I use a radio shack microsope personally, but I find that all of the hairs are brown when most trichomes are cloudy and amber. I would let it go at least two more weeks, maybe even three.
Although some strains advertise 53-60 days flower, I find that atleast 70-77 days does it on sativish plants, while 65-70 days does it on indicas. Just depends though on the grower and the environment.
