From your photos, I would say that this plant is not yet flowering. I've had autoflowers in the past which turned out not to be autoflowers at all - I just had to flip to 12/12 and they flipped themselves within a day or two. I know others will say "ride it out" and that the auto plant will flip eventually, but I can tell you that I've had two outdoor "autos" that never flipped after nearly 6 months and had to be thrown away as they reached the end of summer as giant children!
