Nice setup & buds + rep.
By the looks of her it should yield a bit more than 2 Oz, but i never count my chickens.
Just remember that patience is #1, in a couple weeks, you'll hear alot of "its ready" but if you want the best from your ganja you'll wait it out. That whole, "harvest early for a head high" wives tale is bogus, the high is determined by the genetics. There is an ideal window in which to harvest marijuana, when the tric heads are fully swollen and at least 1\3rd amber, don't believe the hype. Make sure you dry your bud slowly too, it'd be a shame to waste such beautiful marijuana by putting it in the microwave\dehydrator\oven. Take it slow, you have to consider finishing the weed as part of the process. You could have a Cup winning strain and completely ruin it by chopping early and\or quick drying it. Even if you have to buy one more bag to keep you going, and you're just dying to smoke up the beautiful thing you coaxed from the ground, just wait, it will pay off in the end.
not trying to be a bummer\asshole\patronizing, just sharing my thoughts.
Good luck and happy growing.
