Hey there bro, just a couple things for ya here. For flowering you should be at a 12/12 cycle, 12 hours of light and 12 hours of darkness to fool the plant into thinking its fall and forcing it to flower. The signs of being a female are pretty distinguishable. There will be literally 1 or 2 little hairs growing out of what looks like a small "pear", they won't look like anything else on the plant, when you see them trust me you will know. I too just discovered 2 of my plants are defiantely female (pretty darn exciting as this is also my first real grow) Now you have to look really close at first because they will be really small but when you see them you will know. Maybe you may want to get yourself a pocket scope from Radio Shack (bout 10 bucks) that will help ya. The best way I can describe it is a teeny tiny white hair or two. Second thing I wanted to mention is your best bet is to use a good flowering fertilizer, something low in Nitrogen and higher in Phosphate and Potash. I use Tiger Bloom from Fox Farms, it's a 2-8-4 fertilizer 2.0% Nitrogen-8.0% Phosphate-4.0% Potash. Also you may want to consider feeding them Molasses for the carbs they need during flowering. I'll be looking forward to the updated pics, if I see anything I will let you know. Unfortunately I cannot show you mine because my cheapo camera cannot take a close up if it's life depended on it lol Thats bout it from my end I wish you the best of luck man and hope your buds be sweet and strong!!!
