Comment from Green Valley Wellness - Talent, Oregon
While it is highly unlikely for clones to hermy into males, it is possible for plants to become hermaphrodites if they put under stress or if their light cycle is abruptly changed. We are incredibly diligent with who we purchase from and all our vendors are top tier local experienced growers who ONLY clone from females of superior cultivar genetics. Maybe you are mixing up female plant Calyxes with what you think are pollen "balls". This can happen if you don't give auxiliary light before June 1st in our area and that could appear as male to layman. We are quite certain that ALL clones we sell are in fact female!
