Male or Female? Help!!

the first group here is plant three

the second group is plant 4,

plant 4 seems to be the one with male characteristics.... are all my other plants male or what?

i wouldnt smoke the males plants unless you want a headache. put it to better use and make some hash or use a vape.

bump. can someone help me here please

they all don't have those nuts thingy's at the nodes it seems... I took pictures of the nodes and i tried to pull the fan leaves back

I believe that, the last picture that you posted is a male. I am new to this but from all of the pictures that I have seen that is a male.

Plant 4 is definitely a male. I agree with grape swisha, do not smoke him unless you want a headache. So go ahead and make some hash. Also, remove that male from the room IMMEDIATELY! Hopefully he has not had the chance to seed the whole crop. I used to mistake the new leaf sprouts for the white hairs (probably because I was soooo excited or more like stoned), so don't forget to check under the leaves for pollen sacks until you are certain they are not a male or a hermie. Hidden pollen sacks on a hermie it what got me on my first grow Good Luck and happy growing!
Oh, and you need to work on some better pics. it make it easier for others to help you out.
