My New FIRST Plants!

Ok so i'm new to the whole new growing thing and i have 3 plants that are getting pretty big and have been in the ground since the end of may. I was wondering if anyone would be able to estimate at-least how much they will grow the only thing i have been feeding them is miracle grow.
I know its almost impossible to tell how much you can get off a plant but i would like to get a rough estimate. I was also wondering if they were sativa or indica.

Thanks Keep It Green

I forgot to mention they are all FEMALE

Assuming your holes are big enough for the plants throughout flowering and you acquire yourself some nice bloom nutes at least a qp per plant but you could easily get more.
