male, female or dunno?

any ideas?

Here's some other pics

can't tell yet, or at least from the photos. how long has it been in 12/12?

I would say a little too hard to tell still. Give them a little longer and keep posting pics.

there's no obvious signs as far as I can see either,
Today is day 5.
They are in 12/12 went straight from 24/0 and the increase in plant growth is amazing.
I'll post some tomorrow, hopefully it will be obvious :D
