Possible female hairs? & which type of fertilizer to use

[ganjababe1]

So I have two plants that are about 3 1/2 weeks old. How long does it take to tell the sex of the plant? I cannot tell if these are possible female hairs. They aren't white, but they do stick out between the branches. See:

Also, I was wondering if the plants were old enough/look strong enough to start fertilizer. I have Neptune's 2-3-1 Fish and Seeweed Fertilizer and Neptune's 2-4-1 Fish Fertilizer. Which should I use first, and how much to dilute it, etc.

Thanks guys

If you are on a 12/12 light schedule you will know sex pretty soon. Those are not female hairs. All plants have those, male and female. The little green pointy things

What material is that foil stapled to ? I would take the foil down.

No, I'm on 18/6 still. When should we go to 12/12? Do I wait until I see female pistils, or just when it's 1/3 of the growing space? They're only 6 in. and 4 in., so that's why I asked about which fertilizer to use.

If ur at 18/6 now, u will be able to see sex soon enuff. Hang in there..u can even go 12/12 for a few days to find out...then go back to 24/0 to re-veg. Just thoughts man. Nice looking so far..keep up the good work.
