pH-Down 23L
Best pH balancer for hydroponic growers seeking optimal nutrient absorption.
Advanced Nutrients pH-Down is your essential solution for managing hydroponic nutrient solutions and growing media. When pH levels rise too high, this highly concentrated liquid concentrate effectively lowers them, ensuring your plants can absorb nutrients optimally. Maintaining the ideal pH 'sweet spot' is crucial for maximizing yield and preventing issues. Use this formula when pH drifts upwards to protect your garden from potential yield loss and promote healthy plant growth.

Know before you buy
Hydroponic plants can only absorb nutrients within a specific pH range. If your solution drifts too high, your plants will experience nutrient lockout, meaning they cannot access the food they need to grow, which can lead to stunted development or yield loss.
This is a professional-grade, highly concentrated formula designed for efficiency. Because it is more potent than many retail alternatives, you should add it to your reservoir in very small increments to avoid overshooting your target pH.
Yes, this formula is effective for both hydroponic systems and soil-based growing media. It is applied as a soil drench to help correct pH levels that have drifted upward over time.
No, this is a synthetic liquid concentrate. It is formulated for rapid, precise pH correction rather than organic compliance.
This is a quick-release formula, meaning it reacts almost immediately upon contact with your nutrient solution. Always mix your reservoir thoroughly after adding the concentrate before testing the pH again.
