Typical pre-sexing, this is how its supposed to work. If you veg a plant long enough it will show either tiny pistils or little nuts right where the offshoots meet the main stem after 3-4 weeks of hard veg.
Males tend to show a little earlier in general, so don't be too disappointed when a male or two comes through and the rest still show no sign of sex. The ladies will soon be bringing up the rear.
If you are the type of grower who loves using mixed seeds instead of clones or spendy femmenized seeds (like me) but like everyone else males annoy the shit out of you then there are some techniques out there to sway things in your favor.
I've always grown from mixed seed and its been literally years since I've gotten a male when I don't want one. Most gardeners think that the sex of cannabis is only determined by genetics like it is with us, but that isn't true. A cannabis plant largely 'deacides' what sex it is gonna be based on its environment as it goes through veg! Genetics certainly come into play, but they aren't the be-all-end-all and they can be overcome as well.
Lots of gardeners go "fuckit" and start using clones, but I'm just addicted to the vigor, variety and occasionally unpredictable nature of growing from mixed seed. So instead of learning to clone like most gardeners I learned how to always coax out females. Its a bit harder, but you'd be surprised how reliable it can be.
The whole technique is based around the natural plant hormone cytokinin. It can be found in products like Bonide's Tomato & Blossom Set Spray, or a product called Nitrozyme. Foliar application of the stuff happens from shortly after the plants have sprouted all the way up until they start to really bud. Other than that, I follow these rules:
Very blue light through veg (6500K mostly), NEVER top the plants, use passive air-flow (this means don't blow directly on the plants with a fan, they should not be constantly twitching and moving about), use a high-nitrogen ratio in veg (3 parts nitrogen to 1 part P and K) and supercrop, LST, ScrOG or otherwise do something to keep them from being tall & lanky.
Using a technique like this, you will hardly ever see males when you don't want to. The plants just want to be female, its hard to explain it any other way. The cytokinin suppresses early sexual development and unless you get a male (which pop up very early) you will see no sign of sex for up to 3 weeks into flower. You also need to flower a bit earlier than usual because the plants spend longer than normal 'stretching'. They will double in size when you hit the switch at a minimum, often nearly tripling their foliage before they finally settle down and start to develop big, fat, sticky colas.
If you don't beleive me, (and to be honest, there isn't a particularly good reason that you should) then just keep tabs on this thread: http://www.icmag.com/ic/showthread.php?t=135593 And see if I can prove it by getting 5 out of 5 females from mixed seed. Now I've accidentally broken my own cardinal rule (I accidentally topped one of my plants by being lazy with ScrOG) but I'm still confident we'll be seeing nothing but girls.
Stay tuned, I think many more gardeners could learn to grow all females from mixed seed
If you can build a bubble cloner you can make your own colloidal silver. It cost me $20aud for a lifetime supply of silver.Typical pre-sexing, this is how its supposed to work.

I read up on this just yesterday and I agree it's the way to go. I ordered my silver wire before I even finished Phenomenal's thread
You can self pollinate a female and besides getting 100% fems. apparently the offspring are like clones from seed. That appeals to me a lot.
i am still in vegging and i just found a male
is this possible before flowering? i am vegging at 18/6 maybe this has something to do with this? ]= ]= ]=
what a load of bull*hits!!! the sex is determinated when the flower is impollinated, there is no way to influence a plant from seed to become male or female!!
it's like to say "when your girlfriend is pregnant eat strawberrys if you want a female and melon if you want a male"... non sense!!!
