if pix 3 and 4 are the same plant, than yeah, they're males. but the last plant, 3 is a female..The first 2 are one plant and 3 - 4 are another one
that's what you're looking for.. on the cone shaped one, at the very tip, two little while hairs will grow out of it, sure sign of a female.. the males are round like you said, and they lack the small white hairs..Yeah the other pre flowers ones are round and the 3 rd pre flower is cone shaped
I agree with racerboy from what i can tell in the pictures. When you see the white pistols then you will definitely know the difference. They look like tiny white threads in a pair sticking out. If you are uncertain you can wait a little while and be fine. They really will show their sex with time. Until you feel you are 100% certain i would wait to chop. You will know for certain if you wait for them to show you.
Thanks manHeres a picture of a male we had in August with the outdoor grow.
