The plant looks awesome- how many tries is this for you? Don't flip ur plant until u see the sex-2 little white hairs will be evident out of a little sac that will form where the leaves attach to the main stem. It will may take up to 2 months to show the sex-especially because you have provided the plant with such a large amount of soil(i know, I've read most of your posts). The reason for this is 12/12 lighting stresses your plant (yes, the 12hr lite cycle is a stress-12/12 doesn't happen in nature)and if the sex hasn't been determined, it may become a male when u flip it. When making a mom, I never flip then re flip--ie reguvenate a female; the stress will make it weaker and weaker and more importantly it may become a hermaphridite NOT GOOD. Clone your mom(harder than growing seeds) flower your clones, or take clones from the clones(after they vegged abit), flower mom and save 1 of those clones to be your next mom. Go buy a book about growing plants.
