Um...you do know that you have to mix the Miracle Grow with water before use...right...?
How many pots are being used to raise these 7 plants?
If the number is anything other than 7, you'll run into problems.

The ultimate height formula is ok for a generality, but sativa dominants and indica doms have different growth habits. Sat's usually stretch more, indica's less. If an indica dom, she'll likely double in size (or so) when switched to 12/12.
Depending on the genetics of a sativa, strains can tripple their size, or more. Careful with over-vegging, or be ready to bend-n-tie the stretching branches if they get too leggy.

Regarding Miracle Grow Nutes...

Its hydroponic feed but you can water your plants with it on a soil grow too....its fully ph balanced already so u dont have to worry about all that stuff
So MG is the wrong fert, but a hydroponic mix is fine...? I was under the impression that there were different buffers with hydro formulas.
Why not recommend he get the 'right' shit for the job in the first place...? I currently use Fox Farms 3-part for soil, which takes you from seedling to harvest. A 3-part system includes your G-M-B nutes. (1 bottle of each: Growth fert - Micronutes - Bloom fert) Fox Farms even has a 12 week wall-chart reference guide for applying the stuff. Damn near foolproof, were fools not so damn ingenious.

I started-out growing cannabis (many, many years ago) using liquid All Purpose Miracle grow, (soil grows) and with a little adjusting of the fert:water ratio, it friggin' works fine for vegging cannabis. Period. Are the Miracle Grow nutes optimum...? No, but it still provides the nutrients she needs.
Granted, there are those out there that have problems adjusting a fert ratio, and those seem to be the ones that complain the loudest about MG being shit. (or they are simply spouting hearsay) But in a pinch, I still have no qualms about using it if need be. As with any fert, watch your ladies. They'll tell you if you are overdoing it.

It's all a vicious circle...Learn to adapt, adapt to learn. :thumbsup:

p.s. Yield will be approximatelly 1/2 of what you were expecting, and 1/4 of what you need. (Rusty's cannabis corollary #420)
