I am saying that I use FF Happy Frog as a preference. It has organic nutes that are pretty much taken up by the 3-4th week. Then I have control over what, when, and how much I feed my girls. My Buddy swears by MG and he grows out some very good budz. He does not feed his girls until well into flowering b/c the MG has plenty of nutes already. He likes to truly keep things simple. I can say 1 thing for sure, my budz taste better than his b/c my girls have used up all the nutes and what they did not I flush out before harvest. But as for yield MG does a good job. Although he is very impatient and tends to smoke leaves during veg and picks at his budz during flower. Neither of which I suggest, he gets quite a few hermies this way. And, it severely cuts into his yield.
