Wanted to share what container size does to auto's i know that this may seem crazy but i think that roots have a lot to do with what triggers flower, not sex, but flower.
The following plants are F1 cross known as ALF#5, same seed batch as well as same day age. Only difference was that i transplanted the one at sex into a .5 gal container. The other was left to watch the roots and see if it indeed would flower before the sister, and it did.
Day 45 here for both
This plant was the control plant left in the cup and is the exact same day age as the one above
