Whats it yielding like??

Whats up.. i know there no way to tell the yield, cause of so many factors, gentics, food light so on and so on.. but expert opnion on these four plants i know people who have done it before can gestimate. its my first grow what u think im getting at the lowest yield..

 

theres three plants above, the fourth is a loner, i had to spread the other one out to stay a bit incognito.

 

always want more but that seems about right thanks.. im a keep posting bud shots every two weeks so il post a total..

 

any thoughts gestimation..
