1. Mix Grow, Bloom and Micro in ratios shown in chart until the nutrient level you desire has been reached.
2. Always add the Micro to the water first, followed by the Grow or Bloom. Never mix together before adding to the solution tank.
3. Always pH balance your water before adding the nutrients and then pH balance after mixing in the nutrients, to achieve a level of between 5.5 – 6.5. The optimum level for nutrient tanks (soil or soilless) is 6.2 – 6.5. The optimum level for hydroponic nutrient tanks is 5.6 – 5.8.
4. If you are using a p.p.m. meter, the ideal level in solution is between 800 – 1600. If you are using an E.C. meter, the ideal level is between 1.0 – 2.15ms or 10 – 22 C.F.
