FloraFlex Bulky B for High-Potassium Flower Building The frame of a harvest is set in early and mid bloom, when flower sites either bulk out or stay loose. This supplement leans hard on potassium at that window, with a 0-14-43 analysis that pushes 43% soluble potash into developing flowers. It also carries 1% magnesium, 11% sulfur, and a trace of molybdenum, so the plant keeps enzymes and pigments running while it stacks weight. Growers stack it on a base feed to drive vigorous growth and denser structure through the build phase. That heavy dose of K and support minerals is what fills sites out before the final ripening stretch. Water-Soluble Bulker for Early and Mid Bloom The fine powder dissolves clean into a reservoir or hand-feed, so it moves through drippers and lines without settling out. Run 1 to 5 teaspoons per 5 gallons through weeks 2 to 6 of flower, the early-to-mid stretch where bulking matters most. Add it to the water after the base nutrients, such as B1 and B2, have fully dissolved. The potassium-forward blend feeds flower swell and firmness while the magnesium and sulfur back photosynthesis. At 25 pounds, this bulk bag feeds a commercial room across many plants and repeat cycles.
