Dutch Master® Commercial Edition® pH Down is formulated using top quality, pharmaceutical grade, phosphoric acid and as the industry’s strongest pH buffer, is super concentrated to save you money! Use pH Down to decrease your nutrient solution pH for improved nutrient availability to all plants.
The Dutch Master® Commercial Edition® is a range of advanced nutrients and additives suitable for both professional and general hydroponics growers and is proudly manufactured in Chicago U.S.A. in an ISO 9001, ISO 13485 (medical manufacturer) and ISO 14001 (green manufacturing practices) certified facility - a world first in our community!
Usage & Mixing Instructions:
See Usage Instructions & Tips for in-depth root & foliar feed directions and advanced growing advice, and Feed Charts for recommended nutrient and additive dilution rates. Never mix undiluted nutrients or additives together as precipitation (fallout) will occur rendering some nutritive elements unavailable to plants potentially creating deficiencies. Dutch Master® converts EC to ppm using x0.50 calculation. See PPM vs EC in the growers guide.
Add separately to water while stirring, beginning with Sila-Guard®, then Cal-Mag®, followed by Micro, Grow, Bloom, Trich-XL®, Zone® then Saturator® last until you reach desired EC/ppm - measuring preferably using a calibrated meter. To increase nutrient EC/ppm strength, increase dosage volume of Micro, Grow and Bloom maintaining recommended dilution ratios. To decrease nutrient EC/ppm strength, dilute by adding more water. Finally, check pH and adjust accordingly.
Dutch Master® recommends maintaining nutrient feed solution pH for Aqua Feed® and Media Feed® between 5.5-6.1 and Coir Feed® between 5.6-6.2 using Commercial Edition® pH Up or pH Down. When making a fresh nutrient solution, adjust the pH to the low pH point recommended for your nutrient above, as pH may rise over time. If the pH of your nutrient solution approaches the high pH point above, and it’s not time to drain and refresh the entire nutrient solution in the system, slowly add a little Dutch Master® Commercial Edition® pH Down while stirring and checking with a calibrated pH meter or pH indicator strips to achieve the low pH point again. Remember, adding pH Down is also adding phosphorus, while adding pH Up is also adding potassium so be diligent with its use. If the pH of your made up nutrient solution shifts drastically in a short period, it is usually a sign that the plant is stressing. Check for root rot etc.
Warning: Dutch Master® Commercial Edition® pH Down is super strong and should be handled and stored with extreme care! Use protective clothing when handling! Do not inhale! Keep out of reach of children and animals! See the pH Down SDS in the Downloads section for further safety information!
For the longest product shelf life, store nutrients and additives with a sealed cap in a cool, dark, dry area.
