Dutch Pro pH Down Bloom Dutch Pro pH Down Bloom contains 30% phosphoric acid and can be used in the Bloom cycle to reduce the pH of a nutrient solution. Phosphoric acid also provides a source of Phosphorus, which can be used by plants in Bloom. When growing indoors the pH value of nutrients fed to plants needs to be controlled. Plants are able to absorb nutrients more easily at a pH value of between 5.5 – 6.5. For plants to perform to their full potential pH will need to be monitored and adjusted at regular intervals (daily if possible). Adjust pH by adding a small amount of Dutch Pro pH Down Bloom to the nutrient solution, then recheck the pH value, repeat this until the pH reaches the value required Note – pH up and down can causes severe burns keep out of the reach of children. In case of contact with eyes, rinse immediately with plenty of water and seek medical advice Wear suitable gloves and eye/face protection. pH Up and pH Down react violently if they come into contact with each other. Never mix them together. Use separate measuring equipment when adjusting pH values.
