Has any one used fulvic acid as a leaf spray?? Or growth hormones like giberillic acid?? We use them on the farm on cut flowers & grapes. works wonders. I' m going to try them on two plants this summer. A tremendous amount of work has been done by Dr. Jackson (600 page report) on fulvic acid & it's relation to plant growth and humus formation & particulary mineral release in the soil.
