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.
