Say goodbye to nutrient lockout and hello to heavier harvests. Advanced Nutrients' scientists engineered pH-Down with Phosphoric Acid so you can easily achieve the ideal pH levels for optimal nutrient absorption. This highly stable buffer will give you precise control over your pH, even after dilution or adjustments between reservoir changes.

• Recalibrate pH levels with maximum buffers
• Highly concentrated formulas for longer use

Nutrient Solutions: Mix a new réservoir weekly.

Coco: Daily.

Other Substrates: 2-4 times/week as necessary.

Use small amounts when adjusting the nutrient solution to affect the pH level, as required. Use to maintain the optimum pH level of 5.5 to 5.8 for hydroponics and 6.2 to 6.3 for sphagnum moss and plants in containers. For best results, check the pH level daily.
