Myself I went with Humboldts Naturals and I will be using the Fox Farm Ocean Forest and Big Bloom. Big Bloom being the only organic substance they have besides their soil. Big Bloom is crazy good stuff. I use it as directed when I switch them over to the flower room. It soaks the soil in nitrogen based organics. Great stuff. Keeps the leafs green green through out the flowering period.
Always good to hear more people are discarding chemicals for growing purposes.
