Flowering at day 19?

I'm growing Blue Mammoth, its an auto flowering strain. The large bottom leaves have turned yellow, and its developing hairs at the top. This is my first grow. Growing under 100w daylight cfl, plus 54w t5. If this typical at day 19? Its only about 4" tall.

if its on 12/12 its possible, if not its still possible. sounds like its growing fast. but yeah it can happen if your under 12/12 its just more likely to happen sooner like that.

Hence the word "auto". Pics too please!

Ya I got it for its auto flowering characteristic, just didn't think it would be so soon. Its been on 16/8 cycle(when I wake up and go to bed). My mobile wont let me post Pic

i wanna see some pictures i got 3 that are only 7 days old.

Yea post up sum pics...
