Grow Soil Question

Im doing a soil, 3 26w cfl grow for just one plant, i know miracle grow products arent the best for mj but what about the organic mg, i almost bought it is it any good? I know there tons of others (prob better) but should i have a problem free grow with that?

I don't like mg. initially in my grow i was using african violet soil by mg, but I came to find that it didn't have any micronutes in it or anything really. It sucked. I don't know if MG puts anything in their soild that is good for the plant. Honestly.....I think it's just dirt. I switched to fox farm ocean forest.....my plants love it.
