I've looked at your diary and the single thing I can see is that you haven't given her as much light as she needs. Autoflowers are best grown with anywhere from 18-20 hours of light a day and 4-6 hours of darkness. You can try, at this point, to increase the amount of hours they get light but they're really coming to the end of their life soon and so it won't make much of a difference.... but still worth doing.
Next grow, don't give them less than 18 hours of light a day and you'll be amazed at the difference. (Some people even grow them with light 24/7! - I used to do that but am now giving my ladies a 4 hour "nap" every day and they like it - helps them to "recharge their batteries").
Good luck! Enjoy the harvest you get and just know the NEXT harvest will be MUCH bigger! And btw, 12/12 lighting is only used for growing photoperiods... it's REQUIRED for them to "flip to flower" and to continue flowering... if the hours of light increase for them, they will revert back to the veg state - and some growers actually choose to do this for a variety of reasons....
