2-Part Vegetative Nutrient Athena Grow is a simple and clean formula designed for the vegetative stage of growth and for non-flowering plants. Our careful balanced mineral ratios help facilitate optimal plant development including photosynthesis, healthy respiration, and robust stalk and root growth. This 2-part blended liquid formula should be used in equal amounts during the flowering phase to stimulate the rapid onset of bud production, increase flowering sites, and promote high-quality yields.
