Massboost prevents calcium (Ca) and magnesium (Mg) deficiencies while stimulating powerful fruit set and development Calcium and magnesium are in truth just as important as the mac ro elements nitrogen (N), phosphorus (P), and potassium (K) you see on the front of every fertilizer label. Base grow and bloom NPK fertilizers only include small amounts of Ca and Mg which in high intensity growing environments can quickly be stripped out of the feeding solution by your plants. Aptus Massboost fixes this problem of under-supply by providing large amounts of plant-available Ca and Mg. Dosage Instructions Use at 1ml per gallon during the vegetative phase of growth Use at 1-2ml per gallon during the flowering phase of growth during weeks 3, 5, 7, and optionally 8.
