outdoors medical grow general questions

Hi guys, I'm a first-second time grower. First grow got pollinated and these seeds just came up naturally. I think they were the free seeds from http://www.amsterdammarijuanaseedbank.com/ so I'm not really expecting anything amazing, in fact, I wouldn't be surprised if they were hemp. It was pretty cool that I made my own crossbreed though and now i've got tons of seeds of unknown quality, and even some of this one's dad x super skunk. There are three plants here, 4-5ft tall, outdoors. (with another 2ft one coming up)
Will they get much taller during flowering?
Can I prevent them from getting bigger during flowering?
What kind of yield can I expect? Any fertilizers to give it during flowering?
They're a bit bottom heavy on the vegetation, but they should be flowering within the next few months, i just trimmed some growth tips today.
I'm guessing these are a hybrid, with sativa mommies. They're next to some 4 1-2ft tomato plants that have some oat/vetch cover crop underneath it (which should have mineralized into the soil by now for a few weeks) .

thanks dude

bump, can anybody answer my questions?

They will grow taller during flowering usually a foot or 2 depending on the strain. You can keep em' shorter by "SUPER CROPPING". Which is simply bend the tops over sideways.There are a lot of flowering nutes on the market...do your homework on that one. If your lookin' for something cheap Alaska morbloom is cheap and works good. Just make sure you stop feeding 2 weeks before they are done.

keep them shorter by super cropping? you mean for next time?

I topped one of the plants, I just hope my neighbors don't mind that theres a fat cola sticking over their fence and which is a very visible place from their window. Not to mention from the street.

how necessary are flowering nutes? I have barley used any nutes at all so far and they seem to be doing quite fine.

Flowering will commence soon, so, it'll be interesting to see what happen

I feel like because they are so big they need more water than my other plants

I'm going to give them a NPK with a high phosphorus for flowering, can anybody reccomend a fertlizing scheme?

also, at this point in time, should i cut off all these lower leaves/branches off that arn't getting sunlight or are streching far to get it?

You'd think these would be simple questions for a seasoned grower. . .

get you some schultz bloom food at walmart. I only cut leaves when they are dead personally.
