I'm not sure what you are seeing, but I see no sign of sex--new growth can often be mistaken for female pistils though, by new growers. The plant looks too small and immature yet to be showing sex. However, it looks green and healthy, so keep up the good work! However, I would remove the lower lamps. They are most likely mot doing much and plants do not really like the undersides of their leaves lit up--this is something that never happens in nature. It will male your lights a lot more effective if you paint the interior of your grow space flat white. Those brown walls are just absorbing the light. How are you getting 2 1000W lights in a space that small?
Also as this is a bag seed, it is almost certainly a result of selfing, rather than a seed made the old fashioned way....with pollen. So, this plant will have a far greater potential to hermy. So try to keep it as stress free as possible. This will become a lot more critical when it gets to flowering. Seeds that are a result of selfing will be female, but with a great propensity to hermy. Because of this, a lot of us do not use bag seed. It is heartbreaking to get towards the end of a grow and have the plant start producing male flowers and end up with a crop totally seeded with worthless seeds.
