Yes, Sk33tlNnOObs, in "late" veg, the cannabis plant will show it's sex via preflowers. The white pistils will pop out of the top of a teardrop shaped ovarian calyx, which will form first, and the males will resemble a claw. of sorts, at first, then it will look more like a knob on a stick, and then they will resemble a lil' group of bananas(we call em 'naners), these r the early pollen sacks that will eventually open up when flowering begins, and pollenate any females nearby(even within a mile outdoors, via wind), so, don't be too quick to deem a preflower a male, because it could just be that teardrop shaped calyx(or false seed pod) that the white "V"-shaped pistils will eventually spring forth from... Those r the ones u will want to keep and flower out. If u use prunning methods, u shoould be able to keep their sizes in check, and if the stretch does "overgrow" your space, just tie down the taller branches, or stake them down easily, and let your canopy fill in horizontally, instead of the natural tendency to grow vertically towards the light(s)... Usually, around the fifth or sixth nodes is where they tend to begin forming at, too... But, check all nodes from top to bottom, anyways...
