FoxFarm Cultivation Nation pH Down (1 pt) safely lowers the pH of nutrient solutions and water — essential because plants can only absorb nutrients within a specific pH range. If your water or nutrient mix is too alkaline (above ~6.5 for soil, ~6.0 for hydro), nutrients lock out no matter how much fertilizer you add. A few drops adjusts pH precisely. Concentrated — a pint lasts a long time. If your plants show deficiency symptoms despite adequate feeding, pH is probably the problem. Available in Galion, OH.
