Epsoma organic bio-tone soil starter

Anybody have any experience with this product i have looked at it and am currently trying it out its has myco granules thought it couldn't hurt right?

I am using it right now, but I am also trying to move on and blend my own amendments. The stuff is hot and it burns plants easily if you just mix it with your soil without letting it age.
I tried top dressing with worm casting tea and they do fine. Like I said, there is probably a better way to do it and a better person to talk to than me.

yea i did notice it was hot when fresh but after a week sitting and spraying with water and molasses it was perfect.
