Containes two 10 oz packages of Dr, Mittleider's essential mineral nutrients. All natural - comes from rocks!
Just mix according to instructions with readily available products you can find in your area to make 60 lbs of powerful Weekly-Feed. Mix one 10 oz. package of Micro-Nutrients with 4 lbs. of Epsom Salt (Magnesium Sulfate) and 25 lbs. of 13-13-13, 15-15-15, or 16-16-16 to make your own Weekly-Feed. Much less expensive than shipping the completed blend across the country.
