Sorry to hear that your feminized WW cocked-up on you. I don't typically care for feminized genetic backbones personally, but some like them. Depends on your POV. In late flower some of my equatorial girls will shoot naners regardless of stress. WW does have south american in her, but none of my WW ever hermied on me in late flower. If I think I have fertile pollen floating around w/ less than 3 weeks to finish, I typically spray the sacks once w/ plain R/O water to germinate any viable pollen grains and let them finish.
