beautiful sativas! first pic group, #2 ... looks like it may be a male. at the branch internodes, keep an eye out for pre-flower hairs or balls. you can sometimes get a good idea of the sex after week 5 veg, but not always.
hope the light tarp is working well. did you do a frame for it, or just tack the tarp against the house? 100% darkness is key. light leaks or interuptions of the 12hour darkness period can cause other problems (like hermaphites), so be vigilant. your's should finish @ when we are ready to plant here

carefull too, sativas outside can stretch like hell, if worried about height, either top her or train her to grow more horizontally.
mollasses ... GREAT stuff and a secret ingredient for many gardeners ..... contains most of what the plant will need to feed - NPK + trace elements + sugars. also the main ingredient in SEVERAL major fertilizer lines. stick with the dark blackstrap stuff. do some google searching, look around and consider just continuing organic ..... mollasses + maybe some bat guano for flowering nute boost.
*** hahah ... just saw this post on it too .... karmic ....
