2 weeks since germination

Hey everyone. my plant in my hydro system is about 2 weeks into growing, its about 5-7 inches tall, and is just barely starting to grow its third couplette of leaves. the roots are about 9 inches long floating around the resevior and look white and healthy. the stem seems nice and strong, overall looks like a pretty healthy plant. I just want to be 5 steps ahead of anything that needs to be done.

so now what? do I add any nutrients? when do I change the water? and can anybody tell me at what point will I be able to tell weather it is a male or female plant I am growing, I have 7 others growing in soil and am wanting to get a male out of my hydro system as quick as I can if it ends up being male.

If the plant is healthy you should see white pistils or balls by 3-6 weeks, it can take up to 2 months though.
