they look great. nice fat stalks and big thick leaves.update
I finally re-potted the taller one today. Im letting the smaller one stay in the smaller pot until I get more room in the bigger grow room. Still no pre-flowers. I've been pinching the top of the one I re-potted to let the lower branches catch up. Ive given no nutes to these plants...Im starting to think nutes are a sham, and plants only need nutes once or twice in their lil life.
the first pic is the tall one...we'll call that one "darky," because its the darkest plant I have, and the other one we'll call "stubs," because its shorter than its counterpart.
"stubs" and "darky" in all their glory
look on the 8th node from bottom. right where it meets the main stalk. you should see little tiny preflowers. check between the 8th and the 12th nodes.
