What is the optimal Ph level for my nutrient solution?
The optimum Ph level for maximum nutrient availability is different for all elements, for instance Nitrogen has a different optimal Ph range than Phosphorus. The optimal Ph range can also vary due to medium and growing method variances, that is to say soil vs. rockwool or Aeroponics vs. Ebb and Flow. Therefore, we recommend a Ph range that is most inclusive, from 4.5 to 6.5. The Ph level we recommend for the most inclusive beneficial range is 6. We do not recommend using Ph up at any time. If your water is acidic, i.e. RO water, adjust your water to Ph 7.0, then add nutrients. Utilizing this method, the elements are less likely to be locked out because of a severe Ph swing. 3) What PPM/EC is optimum for my nutrient solution PPM levels vary from situation to situation. Our recommended vegetative mixing rate can run as high as 2000 PPM, while a flush mixing rate is much lower. Please refer to the CES product mixing and reference chart for specific recommended PPM ranges for our products.
