1 Gallon bottle 

FloraFlex Nutrients Cal + Mag + Iron is designed to complement the FloraFlex 2-part base nutrient formulas

The Floraflex Nutrients base feed already contains all of these elements however when using LED lights, reverse osmosis water / soft water we highly recommend using a 'Cal Mag' supplement. 

Some plants may require more of these elements under rapid growth and/or developmental phases

The product corrects common deficiencies when using reverse osmosis water, as well as plants grown in coco coir, rockwool and/or any hydroponic growing media.
