Important Mixing Instructions
To prevent nutrient lockout and precipitation, Part A and Part B fertilizers should never be mixed together in concentrated form.
For best results:
- Fill your reservoir or mixing container with water.
- Dissolve Part A completely.
- Allow thorough mixing.
- Add Part B separately and mix thoroughly.
- Adjust pH as needed.
Proper mixing ensures maximum nutrient availability and helps maintain a stable nutrient solution.
