Hey, buddy. Yes indeed, little problem.
An automatic that doesn't go off after 6 weeks is that there's a problem (even for a stressed plant), and you're now 10 weeks old.
It is possible that there is a genetic problem (even if it would be very surprising, I think it's possible).
If this is the case, it means that your plant is a photoperiodic and that you have to pass it in 12/12 in order to trigger its flowering.
Once it is on 12:12, your plant should start to develop its pre-flowers within a week.
For nutrients, reduce them a little for now, but when the pre-flo and then the Flo arrive, your plant will need more and you can resume its fattening program. Peace. ✌️
Let's grow 🤘😜
