"Shunned" is a bit harsh.  lol

First grow? Check it out. A lot of us have and do use it. A lot of us started growing long before the online seedbank or grow shop, so we used what we could find.

Be careful, it's easy to over do it with MG. Watch you plant, it'll tell you what's going on.

How bad can MG be, if you've made it this far, and the plants look great??  If it works, stick with it until you find something better.
