you start sexing when you switch the lighting to 12/12, then youll start to see sex with in bout a week

i know how, i was asking when to start. i dont know when to judge if theyre ready to sex or not. as for how i know that.

you mean when should you start to flower?

if your asking when they are going to show sex, that will happen whenever u decide to put them under 12/12. You can do it whenever you want, otherwise you wait for preflowers.

what if you are growin outdoors how many week estimate?

after looking at your grow, you better wait a little bit before you flower, they need some healthy growth, get more light. Otherewise they look like they rexovered well.

Outdoors it depends on the strain, ussually about 3months is my guess, but I dont know 4 sure
