flower those girls for sure. I dont let mine get more than 5 or 6 nodes high before budding, they will get bigger than you think. I made the mistake of talking a buddy into growing some for me with my equipment, told him what to do, etc. He worked graveyards from 2 pm and I got off work at ten so I never saw them. I showed up at harvest time and the plant grew to the ceiling and into the lights and got burnt to shit. He did a horrible job!! but they do get big and fat I promise. good luck
