General Fertilizer Considerations for Cannabis Production

General Fertilizer Considerations for Cannabis Production Professor DeBacco General Fertilizer Ratio and Dilution In general a 2-1-2 (N-P-K) ratio is often considered to be the standard for cannabis Regarding concentrations manufactures recommendations should provide the starting point. Fertilizer Concentration Check In general an EC (or ppm) meter can be used to check the concentrations of nutrient solutions. Electrical Conductivity (EC) or Parts per Million (ppm) Meter- measures the salts in the water Tap water example = 0.4 ms/m or ~200ppm Nutrient Solution example = 1.3 ms/m or ~650ppm Using The Meter Goal is to measure water being given to the plants and also what is coming out of the container/substrate This will help growers dial in their feeding concentrations so they can maximize plant production while also limiting nutrients lost/wasted.
