Cant view the pics, but it is easy to tell the difference. If its female, there will be 2 pure white hairs that are just under 1cm long. If it's male, there will be balls and no hairs. But dont throw away if they are starting to swell as the hairs come out of lumps that in really realy flower can look like balls, just wait a while longer. When the balls are formed, they look like balls and you wont be mistaken

Just saw the photo's and its really hard to tell, tho those 'swellings' look like balls. There too muchlight in the photo, can u take any more
