My question firstly would be how long u had these in flower for already??
Reason i say is, tho i thankfully can't spot any male balls anywhere but i'm not sure i can see any female hairs either (??). I might be wrong but i can't see any sign of sex yet. And be aware those 2 little prongs on the sides of the stem by internodes (might be called stipoles, but can't remember at mo) aren't signs of sex, they just grow normally anyway.
The 1 or 2 female hairs u want it to show are normally quite obvious long, thin, slightly furry hairs, abit like a white eyelash or a moths antennae. Some plants can take 2 weeks from switch to 12/12 before they start showing.
Anyway, like i say i may well be wrong, but hopefully someone more experienced may be able to tell.
