Sorry but I cant tell sex in any of those pictures...try to take an up close picture of the where the branch and the main stalk meet. (The node.) Up towards the top of the plant. Females look like this...with a small tear dropped looking flower and two white pistils sticking out of it.
Males look like this... A little stalk with a ball on the end is how they look at first. Notice NO PISTILS.
Sorry, cannot tell from the pics supplied. Could you please ignore the Foliage, and get some Closeups of the "Crotches", where the branches come out of the main stalk? That's where Male "balls" will occur, IF they do. BTW I don't see any of those yet.
How far along is this grow? Looks to be over one month old. Photoperiod?
