Sex my Plants ...PLEASE!!

I cannot tell if these are just the formation of new leaves, or preflowers. The pics are of the same plant. It's been in flowereing for one week or so...If it turns out to be a male, does that mean it has already pollenated my crop? How long after the initial appearance do I have before they pollenate? Thanks!

Hard to say looks a bit young to be sexing..

no it wont just pollinate your crop immediately once sex shows. Just pull the plant once u see balls for sure and itll be fine

Those are leaves...Those wierd finger looking things in pairs opposite the nodes...Next to those is where the Staminate Primordia, or "PRE-FLOWERS" will develop, WHEN THE PLANT REACHES SEXUAL MATURITY. This is different for every strain. You can cheat by running a 12/12 for a couple weeks, or better yet, cut a clone or two and flower 'em...
