i would probably cut it. that is now my policy with hermis. at one time i tried to keep them, picked and seperate.
but.. ive had a hermi plant that was GREAT smoke. and it produced seeds that were fem, and great smoke. still that one hermi was the only plant going at the time so i grew it out and tried to pick all the balls. one of 10 seeds i planted from this plant went hermi, from light stress i think. i seperated that hermi and kept it clean, for 3 days then the light fell on it and i had to harvest right then a couple weeks early. it was decent bud. kinda seeded up. my main harvest was nearly unaffected cuz i got it out quick
