how early can you tell the sex?

one of my plants is a week and a half old about 7 inches wide and 4 inches tall... is there any way to tell the sex already. Can anyone give me a example of some females and males and show me how to tell wich is wich .

there is no way of telling this early, some people say that the males are taller to drop pollen which is right however my tallest was a girl!!

Just another urban legend, lol. The only way to tell what gender you have is by flowering. And then it takes a week or two to show. You could always switch back to veg after you find out, but that stresses the plant and cause hermaphrodites. Up to you tho!

wooo this is my first time and all my plants look like that female pic so out of 11 random ass seeds i got all (baby mamas)thats what i call my soon to b clone mothers lol, but is that even possible?

You are probably looking at the part I have marked with an X in the attached photo, all plants have these. The part that shows your plant is a female is what I have circled. Clear hairs. Your plants are too young to have these yet, especially if you havent switched to a 12/12 light schedule yet.
Show us some pictures of your plants for more help.

It's not an urban legend. Males tend to be taller and have half as much foliage. Fact

I've done plenty of weeding out males.. before feminized seeds were available, and 90% can be pulled before they ever show sex

oh ok mine r still on 21 hrs of light ima put sum pics up tomorrow when would b a good time to switch to 12/12 my plants r 1 mo old

yes that is true, my males were very tall n lanky n the leaves were spaced apart alot more then the females...

Males are usually taller with wide node spacing....Usually. Your plant has not even chose a sex yet. They dont do that until about 3 weeks unless they are feminized. To promote more females, Veg with Blue spectrum light like MH or 6500k CFLS, Provide healthy amounts of nitrogen and Introduce plenty of CO2, This will promote fems.

It can show within a few days after 12/12 if the strain and plant is mature enough. I flowered my plants at only 10 days vegging and it didnt show sex for about 10 days. And when it did show sex. There is no mistake. You can tell there is a hair growing out of a plant. Its simply visable. Just in my 2cent.
