I am in the same boat as judydu2, I used it along with a few other products, plus we have had more rain this year than I can ever remember. Yes, I do have more buds than ever and the plants have grown like crazy, but still I have more plants than ever, and they are mostly very young, so I expect to have more buds as the plants develop and mature.
That said, I "feel" the Milorganite (along with the other products did do some good) I just can't specifically say it was the Milorganite that can take all the credit. I can say, I certainly don't feel it did any harm, and I do think it does help to temporarily keep out the critters for a few days.
I have decided (and laid out my new plots) to use three feet center to center for my plantings and three feet between rows.
