A girl! So soon?

Hey everybody, my grow was started from seed on 4-20. I just looked at seen this one plant has white hairs see. They have been on a 16on8off schedule. This one is in soil, out of the 12 its the only one showing any signs of sex. Normal? Thanks in advance for any wisdom passed along.

Yea all is normal man it's a little pre flower showing the sex of the plants. The others will start as well, soon I'd imagine.

Im sure you know the hairs mean a female ( no disrespect intended)

how tall are they 420 to today is a good haul in the veg room

If I'm not mistaken, that is an auto-flower correct?

not sure if its auto-flower, at first I was told it was sour diesel, but its bag seed out of some dank.Killer head high so hopin my end results have the same affects. check my journal for sizes, I posted measurement pics today actualy. about 8inches up to 15 inches. I could stack 4 or 5 easily so im not worried about the growth spurt, bring it on! The plant I topped is actually tallest haha, no lst just wanted to get a feel for how they grow naturally more or less.
