Trace elements such as iron, manganese, zinc, copper, boron, or molybdenum are needed in significantly smaller quantities than macro or secondary nutrients, but are nevertheless essential for the plant. They control numerous enzymatic processes, metabolic reactions, and indirectly also growth, leaf color, and vitality.
In cannabis cultivation, problems with trace elements often do not occur in isolation, but in connection with pH shifts, nutrient lockouts, excess salts, or a weakened soil life. In well-functioning living soil systems, trace elements are usually made available through humus, minerals, and biological processes.
The goal is therefore rarely to aggressively supplement individual trace elements, but rather to build a stable, mineralogically and biologically healthy system in which micronutrients are continuously available.
