Preflowers!! @ what age?

How old does a plant have to be to start showing preflowers? I have 13 White widows all of them are 42 days into veg. There is what I believe to be preflowers but I am not sure. Can someone please tell me If I am looking in the right place? and what they think they are?

hey man i looked at the pics and two me in all the pics they are females you got the hairs soon it should flower.

It shouldnt flower yet its still on 18/6????

You can flower whenevr your ready mate, when they get to the size you like, you flower.

People flower after 1 week veg.

were u lookin to see if it was a male??? what do you look for to see if its a male cause I had two plant's turn homo on me and this time id like to brake them in half before it nuts all over my closet

Males grow pollen sacks in the same palce that femailes grow buds

heres a pic

Well I know you can tell from preflowers but I have read that females dont show preflowers until they are under 12/12 but I have read the opposite too. I am confused as to wich is true? Is this an accurate way to tell? can the females be pollinated before switching to 12/12?

yes a fw of them deff appear to be female..cant say for sure on all of em but yes you have some ladies..about flowering, you can force flower whenever you wish. My plants are 27 dyas old, been on 12/12 for a week now, just saw my 1st female this morning, also i believe i discovered a male but thats part of the game..pics on the way,

I dont think they show sex until flowering, but im not sure.

does anyone know of a site that explains how to tell the difference I tryed the FAQ's nothing if anyone could help that would be bad ass

It is in the FAQ.
