Jack's Dark Weather formula is one of our most popular when growers are looking for a way to increase calcium into their fertility program. An ideal product for growers who want a non-phosphorus, high nitrate product with calcium. Alternate with 20-10-20 Peat-Lite or use as a "finisher" for flowering plants like poinsettias. This formula has the traditional micronutrient levels needed for general production.
For Use On: All plants
