my setup and some questions

hi guys, i posted about 7 weeks ago about my experiment i was running.
different grow mediums that pretty much work well with me and my lifestyle.
pretty much between promix and a bubbleponics setup. im on week 7.
i have a couple different strains and lighting.
Greenhouse
ultra haze 2
barney farm
lsd
vanilla kush
Ministy of cannibis
white widow
white rhino
master kush
hindu kush

im using optium hydroponix complete line up.
i have 5 lights in total
2 400w mh
3 sunblaster digital 600w with super mh and super hps bulbs

heres some pics

when should i be flowering, my bubbleponics setup is crazy, i didnt expect it to get so big so fast. next time im only vegging for a month. I know my plants in promix are behind compared to the others. Am i still good to flower all together, or should i still wait?

oh yeah id flower now, most plants will finish about twice the size they are when they are first flipped. by the looks of it most of those will be monsters.

I gots LSD and master kush. LSD stayed short and bushy. Nice fat nuggets.. master kush is a teenager

thanks guys for the responses, ur input is greatly appreciated. im going to start flowering immediately. hopefully i get all girls (all my seeds were feminized)
