Take a good basic fertilizer program to a higher level for flower and fruit-bearing plants with new Sonic Boost Flowering Fertilizer (0-39-27). This specialty nutrient is a water-soluble powder that provides the phosphorous boost needed during a plant’s critical flower and fruit development phase. The formula also helps to maintain the ideal potassium balance required by a plant to metabolize essential nutrients required for overall health and development. Sonic Boost should be added to nutrient solutions at the first sign of flowering and added weekly to the feeding program until plants mature or are ready for harvest.
