Is my photoperiod actually an auto??

Yes, since she is flowering under a 20/4 lighting schedule, she has to be an auto. No true photo period plant would flower with 20 hours of light. Also, I would ease up on feeding her grow nutrients, she does not need both "flower" and "grow" nutrients at the same time. Too much nitrogen during flowering can cause overly leafy flowers. Hope this helps,... Organoman.

Thanks for your question. I've the same problem with my gorilla faster BSF. Have a label "foto" but i don't know. I put her together my others autos, og and ultra moahm ram and with 30 days be starting flower

If its truly in a 20/4 photo period then that’s not a photoperiod strain and must be some heavy ruderalis influence or straight auto. Guessing you don’t have some landrace afghanica/hindu/neplali genetics or else that could be a possibility, even though it’s in 20/4 light. Human error with seed banks happens all the time, fwiw.

It's very possible. Stresses like weak lighting and falling temperatures can also push a photo into flower, but its more likely that your breeder made a mistake.

If it's flowering under that light condition then yes. It may be a mislabeled seed so who knows what it really is! 🤘😤
