super cropping for an 11 week grow is going to be impossible i'm afraid. supercropping itself will add at least a week of veg from this point , so unless you think this plant flowers in 6 weeks, you're beyond the mark. Why not flip her now, as she already looks great, two/three days of darkness then the 12/12 to make sure she knows it's time. you're on a tight schedule so you dont really want the plant to be confused about when to start flowering. or maybe just supercrop now and flip right away... but it's gonna be tough the 11 weeks... sorry for the bad news, but such is the truth ... hope this helps ! π
