OG Kush is a sativa dominant strain, which is kind of weird considering its called "Kush" which is generally indica. I think if you think she's not ready then wait it out, because the male flowers will take at least a couple weeks to mature, then they have to burst and then it will take a couple more weeks on top of that for seeds to set, so as long as you harvest in the next couple weeks you should be good. But if they are already growing and almost mature I would chop now, otherwise you will get a bunch of little baby seeds in your crop which is probably more annoying than full sized seeds because its almost impossible to get them all out.
