Picture says 1000 words lol. But as a newb myself, I will pass what I was told. YOU WILL deff know when it's a dude or a hot chick. I was all tripping that I wouldn't be able to tell its super obvious. Basically if there is a nice white looking hair growing out of the node she's a keeper. If there are balls growing on the nodes.... Well to each their own lol. Ya dig?
N ps I vegged for 51 days and they didn't show sex until 10 days into flower. From what I read, different genes will show sex at different times. If you wanna save time I believe you cut a clone as soon as you can and flip to 12/12 this way you can keep vegging and if she's a keeper you keeper. If she shows she's a dude. Toss it
Gluck happy growing
