Target nutrient levels (final solution)
These are just basic recommendations: general starting points in ppm. They load N-P-K and the key other nutrients for the crop and stage, so always fine-tune for your water, cultivar, and system.

How to use this
Pick a fertilizer for each row.
Set its Base element to the one nutrient you want to dial in to a number, usually N, P, or K. Then enter that Target ppm. The calculator doses the product to hit that target, and every other nutrient in it follows automatically in the product's fixed ratio.
Check the Resulting Profile and Mixing Guide below for your totals and exactly how much to add.
Example: choose Calcium Nitrate, set the base element to N at 150 ppm. Its calcium comes along in ratio, so you don't dose it separately.
Example: choose Magnesium Sulfate, set the base element to Mg at 50 ppm. Its sulfur comes along in ratio, so you don't dose it separately.
