DIRECTIONS:

• Fill your reservoir with clean water before administering any nutrient or additive.
• Make sure that the water level in your reservoir is sufficient to effectively flood your desired area or table.
• Potential nutrient lock-up can be avoided by adding the Micro before the Bloom and Grow.
• Always wash your measuring cup immediately after adding and stirring in each nutrient.
• Never mix any of these nutrients together in their concentrated form.
• After adding and stirring in each nutrient, check and adjust the pH to between 5.0 and 6.5.
• Always check a small sample of water, not the whole reservoir.
• Not all meters will read identically, Humboldt Nutrients tests are conducted with a Hanna HI9813-0 meter.
• Keep the water temperature in your reservoir between 66 and 75 degrees F.
• Drain your reservoir and pumps at least once a week to prevent any salt build-up.
