Fo sho that second pic is female. You will know it for sure when you see it budding bro, its extremely easy to tell once flowering has started.
So after this point, should I expect to see any changes in the plant soon? Or will it stay in this state for a while?
Honestly, I'm suprised these plants even survived. I got them from a friend, and put them in my back yard. They were really weak, I didn't let them adjust to the climate at all, and it rained for 5 days straight after I put them outside.
They were drooping like hell, so I had to support them with twigs. After a few sunny days, they got stronger, but almost all the leaves were eaten by bugs. I'm not kidding... One of the plants had no leaves anymore.. it was just a long stem! I almost threw it out, but decided to give it a chance. I've really done nothing special to these plants, so I'm not expecting much from them. It's really great to hear that they are female though. Anyway, that was a long ass story.
