Nutrient Profile Calculator

About The Calculator

Plant nutrition is based on a total of 17 elements, divided into Macro, Secondary, Micro, and Trace nutrients. The first set of three come from carbon dioxide in the air and the water they drink, and include carbon, hydrogen, and oxygen. Plant nutrition is a difficult subject to understand completely, partially because of the variation between different plants and even between different species or individuals of a given clone. Elements present at low levels may cause deficiency symptoms, and toxicity is possible at levels that are too high. Furthermore, deficiency of one element may present as symptoms of toxicity from another element, and vice versa.


The purpose of this Nutrient Calculator is to assist growers with finding the ideal Nutrient Profile for cannabis growth. This version of the Nutrient Calculator is Version 1. The Target Profile is based on the findings of CannaStats, and is based loosely on the Lucas Formula. The Recommended Profile Target is as follows:

Users of the calculator are certainly able to set whatever profile they prefer, but it continues to be shown that this formula for both Macro and Secondary nutrients creates an optimal balance for the entire plant life cycle.
