pH levels and concentration of the nutrient are very important for the roots. If the pH is wrong, the roots will not be able to absorb the right minerals. If the concentration is wrong the plant will run out of food reserves, and can even suffer from permanently damaged roots from high nutrient concentrations.

Accurate pH & Nutrient Management Tools for Better Growing
Maintaining the right balance of pH and nutrient strength is essential for any successful hydroponic system. At Holland Horticulture, we stock a professional range of pH meters, pH pens, and EC pens designed to help growers monitor and control their nutrient solution with precision. ...
Whether you're growing in coco, hydroponics, or soil, consistent pH and EC readings help ensure your plants absorb nutrients efficiently, avoid deficiencies, and reach their full potential.
Why pH & EC Matter in Hydroponics
In hydroponic systems, there’s no buffer like soil to regulate nutrient availability. If your pH level drifts outside the optimal range, your plants can’t absorb key minerals—even if they’re present in your solution. Similarly, if your EC (electrical conductivity) is too high or low, you risk underfeeding or overfeeding.
Using tools like a pH meter, EC pens, or combination meter helps you stay in control and avoid guesswork.
