mircale grow nightmare

used mircale grow for my first grow and had all kinds of problems from spotted leaves to fungus gnats to in the end 3 of my four plants turned hermi 2 weeks from harvest.
my question is what is the best sterile planting mix and where can i get it.

i like fox farms ocean forest it has never done me wrong and has all kinds of good stuff in it for your plants. you could get it from your local hydro shop or off internet

sterile stuff lets any old thing in.
baddies have to fight their way in with this stuff

Ive used miracle grow for awhile now and have never had any problems with it. Maybe you strain was very sensitive to nutes and/or you used too much nutes???...

Though I use miracle gro granules that dissolve in water for my feedings and swear by it, I have heard that their soil is not very good and prone to gnats and the like. I simply used regular potting soil, manure, and perelite in a ratio of 5-2-5 and my plants are doing phenomenal.

I too never had much prob with MG but did have gnats ....but they're fairly easy to control.....Most people overwater when using MG which cause most of the probs......
AAMOF....MG Organic was one of my best grows......Mg gets a lot of bad press mostly because users don't have ht epatience to use it.
Now I use Humboldt Soil and Bio-Bizz.....tremendous grows and yeilds....
