Know before you buy
Because this formula is highly concentrated, you should start by adding a very small amount at a time. Always stir your solution thoroughly and re-test the pH before adding more to ensure you do not overshoot your target range.
For most hydroponic setups, you should aim to maintain a pH between 5.5 and 5.8. This range is specifically optimized to ensure your plants can efficiently absorb the nutrients provided in your solution.
Yes, this pH adjuster is suitable for both hydroponic and substrate-based growing. For plants in sphagnum moss or standard containers, you should target a slightly higher pH range of 6.2 to 6.3.
Nutrient lockout occurs when the pH drifts outside of the optimal range, preventing your plants from absorbing essential minerals even if they are present in the water. Daily monitoring allows you to make minor, proactive adjustments before these imbalances affect plant health.
Advanced Nutrients pH Up is designed specifically to adjust acidity without interfering with the nutrient profile of your mix. It is a stable, concentrated solution meant to help you maintain the balance you have already established.
