Auto not flowering

This one just won’t pop

This recently happened to me. Turned out I had ordered photo seeds instead of auto seeds. I just started 12/12 lighting on it and it’s starting. How old are your plants? Any preflowers/pistils showing?

This one was always kinda scrawny not bobs genetics these are from crapking the others are flowering note they did replace the first order which was70% non germinate the I don’t see any positive Id gender
Thanks for your reply

First sprouted 2/17 skinny stems large leaves

If it’s an auto, you probably slowed her down with your topping. I topped some last year. I won’t top autos anymore.

Autos do best when left alone is what I’ve learned…
