Emerald Harvest pH Up - 3.79L This weak base buffer fixes imbalances in nutrient solutions and hydroponic systems, keeping plants under stable conditions. When the pH becomes too acidic (low), simply add the required amount of pH Up to bring your reservoir into its ideal range. The formulation is gentle enough not to harm the substrate and only needs a small amount to serve its purpose. With a steady pH, plants can grow without stress and are less susceptible to deficiencies or “locking out” of available nutrients. Fast, gentle correction The Emerald Harvest range is fully buffered and growers should rarely have problems with fluctuations if used correctly. However, should levels fall too low, a small amount of pH Up will increase the pH in seconds. No stress to plants Correcting your pH too strongly or suddenly could lead to just as much damage. Plants can become stressed by unexpected changes. pH Up uses a weak alkaline base to quickly, but gently, bring levels to their appropriate range. Unlike stronger solutions, it is friendly to the root system and surrounding beneficial bacteria. Where to use Emerald Harvest pH Up? Use in any growing media where the pH is too low (acidic). This is generally identified by a pH reading under 5.5. Plants may show: Brown spots; Tissue necrosis; Chlorosis (where the leaf veins remain green but the rest of the leaf turns yellow); Leaves that are tinged red or purple in colour. These may be signs of other common plant diseases, so it is always best to conduct a pH test before attempting to correct levels. Mix into your usual nutrient solution and apply during your usual watering routine.
