Looking great, nice growth. Nothing much to do but sit back and let it grow a few more days. Then start flowering and before you know it you'll end up with some nice buds. Just care for it treat it right and you won't be dissapointed.
Nice job with the training and carbonated water. This should really speed up growth and help you out. I would wait untill your plant reaches the same height as the timer meaning its level with the top of it. Then put your screen up and begin to flower. Your marijuana plant will reveal its sex...
