New closet grow

I currently have a nine plant garden under a 400 watt mh/hps,
i am using iguana juice grow and bloom by (advanced nurtrients) and keeping my ph around 6.6 / 6.8 i just started my 12/12 cycle two days ago after 30 days of veg and my tallest plant is about 13 inches or so and they are all really bushy on five of the plants all of the lower branches have met up with the top so its going to be quite nice having so many tops on each plant! I have positively identified four female the rest unknown?

My question is can you clone a plant once put into flower cycle?
And is my ph good for an all organic grow?

And these are just seeds that i have collected and the real bushy plants are some good genetics and i also have a crazy sativa that is unlike the rest of the plants i really hope its a girl ill have pics soon!

your ph is ok
and yes.......you may clone while your plant while it's in flowering......

Well thank you much manny ramirez! At a certain point it would probably be too late to clone though right? Would i be ok if i cloned when they are in the third week of flowering or will that stress the little clone out to much trying to covert it back to vegetative state??
