How to use the recipe

The values above are the target element concentrations in the final solution. To obtain them from your fertilizers, click "Open in calculator": it computes salt weights for the needed water volume and starting EC.

When raising EC, increase all elements proportionally except phosphorus. Keep pH within 5.5–6.5 for most hydroponic crops.
