I'm growing in Pro Mix, which is soil less, with some manure added. Pro Mix already contains a small amount of beneficial fungi, but I also add some Myco Maximum to compensate for the manure. I've been using chemical nutes and know that certain chemical nutes can kill the fungi. So I checked with Better-Gro, the nutrient manufacturer to see if that was a problem. It's not. Their nutes are a lot stronger, 20-14-13 and 11-35-15. I start off 1/4 strength at week 2 and increase to 1/2 strength, with the occasional full strength feeding, especially in bloom. I also feed humic acid, micronized trace elements and some PK13.14 on occasion. Molasses also. I mix it all together and use it every watering. This mix does require a good flush at the end or else there will be an unpleasant taste to the cured buds. I just bought some GH nutes that I'm going to try on my next grow. If I don't see a significant difference I'll stay with the Better-Gro as they are available locally and relatively inexpensive.
