I wouldn't worry about it too much...If you have some cuttings in the flower room, you will know soon enough what sex they are. I don't see anything that would indicate male or anything, so you'll just have to wait it out. There are a number of ways to "pre-sex" a plant.

1) the seed itself. If the seed has a concave area where it broke off from the plant, it is reportedly highly likely it will be female. Not 100%, but likely. If it has a level or bulbous look at that particular area of the seed it will likely be a male.

2) The early seedling. Emiliya did a study earlier on here that she claimed if there was a red streak in the early sprout stem, it was likely going to develop into a female. Straight up green stem and it was likely a male.

3) where the branches meet a larger stem, there are likely to develop a small bulb and 2 hairs...likely a female. Ball sack and balls....well, that should be obvious...it's a male.

Other than this or if you've missed those windows to determine sex, the sure fire way to find out is stick em under 12/12 for 2 weeks and then you will know for sure.

Hope this helps, but you must remember, plants grow at their pace, not ours...we would all like to veg for a week and flower for a week and get 10lbs per plant of killer bud, but it just don't work like that. Patience is a virtue, be virtuous.
