Did you start it from clone? If not keep your fingers crossed that it won't be a male.
These questions about yield are kind of stupid. All you get is a bunch of GUESSES from people who think they know it all.
Yield depends on strain, nutrients, medium, light source, temperature, initial size of vegged growth, method of growing (ebb&flow, drip, aero, etc.), and techniques (lst, sog, scrog, supercropping, etc.)
I don't want to rain on your parade. Just warning you that there are lots of people on here who don't know shit about shit but they think they do. With that said I have come across a hand full of growers on here who are very knowledgeable.
