Hello ! Put her under a 12/12 light schedule because If after 9 weeks she's still.not flowering It must mean that she's a light sensitive strain and not an Autoflowering ( it happens some times) . Autoflowering are ruderalis crossed with indica/ sativas or hybrids so sometimes and even with a good selection from the breeders , some plants keep the photoperiodic genes. I hope it will help you 😁👍
