Anyone Wanna Try and sex these guys for me?

ok so i'm a newbie Grower.
Thought i would start off small and go with 3 plants but i have not been able to sex them and they have been in the flowering cycle for approx 2-3 weeks,
if anyone can take a crack at what these guys are +rep for you
also could you explain a little why you think they are male/female? (i won't hold you to it if you're wrong )

3pics of each plant(2 for the last one)

 

looks to early to tell , did you put them straight into flower ? whats the total age including veg time ?

 

picture 6 looks almost like its getting a bud spot but i cant tell

 

they are about 2 months old and i veg'd them with 20/4 until they were a little over half the size i wanted them to be after Flowering since my grow space is limited.

so you recon to early to tell?

 

shouldn't be. i would say you will be able to tell soon

 

It is too early to tell at this time. But 3 weeks of flower is generally the time frame.

I think they are all female! That's for your benefit. Peace

 

Yeah thats what i was thinking which kinda threw me of since i have never seen a male and was expecting to have at least one
Looks like i have a couple more weeks of waiting till I'll no for sure!
