Calcium is a secondary essential macroelement that helps lengthen roots and build strong plant cell walls. Symptoms of calcium deficiency are sometimes noted in plants, especially those grown in coco coir.

Chelator/chelated micronutrient

Some of the microelements needed by your plants for healthy growth, such as copper and iron, cannot be easily absorbed unless they are chelated (i.e., they form a bond with a larger, organic molecule). Chelated micronutrients are often combined into complexes, so they can be absorbed and used by the plants. A chelator is the […]


Chemical symbol: Co Cobalt is a naturally occurring trace element. Considered an essential component of several enzymes and co-enzymes, it has been shown to affect growth and metabolism of plants by interacting with other elements to form complexes.


Chemical symbol: Cu Copper is an essential micronutrient that assists plant growth and metabolism. Symptoms of copper deficiency are twisted leaves and stunted growth.

Essential element/nutrient

The 14 essential elements (also called essential plant nutrients) are those your plants require in order to grow. The three primary macronutrients are nitrogen, phosphorus and potassium. The three secondary macronutrients are calcium, sulfur and magnesium. The micronutrients (also called trace minerals) are boron, chlorine, manganese, iron, zinc, copper, molybdenum and nickel. Plants also require […]


Chemical symbol: Fe Iron is an essential micronutrient that helps chlorophyll form in your plants. A plant uptakes iron in its oxidized form, preferably by means of chelation. Symptoms of iron deficiency include pale, yellowing leaves and dieback.


Chemical symbol: Mg Magnesium is a secondary essential macronutrient, it helps your plants activate enzymes and metabolize carbohydrates. Symptoms of magnesium deficiency include older leaves suffering from chlorosis and younger leaves failing to thrive.


Chemical symbol: Mn Manganese is a micronutrient that activates enzymes in plants. It also is essential for plants during photosynthesis in order to manufacture chlorophyll. Along with iron, manganese works to create chlorophyll.

Micronutrient/trace element

The essential micronutrients (also called trace minerals or trace elements) are boron, chlorine, manganese, iron, zinc, copper, molybdenum and nickel. Although required in lower quantities than primary and secondary macronutrients, they are just as essential for plant growth.


Chemical symbol: Mo Molybdenum is an essential micronutrient that helps plants utilize available nitrogen. A minimal amount of molybdenum is required in plant tissues for normal growth. Crops high in molybdenum can be toxic to ruminant animals.


Chemical symbol: N Nitrogen is one of the three primary macronutrients. In gardening, nitrogen is the element that is most often credited for strong vegetative growth. It helps plants grow vigorously and produce a heavy yield. Among other things, nitrogen is essential for the synthesis of amino acids, which are the building blocks of proteins.


Chemical symbol: P One of the three primary macronutrients, phosphorus is essential for healthy plant growth. It contributes to developing long roots for better access to other nutrients. Phosphorus also helps plants use energy for fruiting and flowering. Symptoms of phosphorus deficiency include slow or stunted growth and bluish leaves.


Chemical symbol: K One of the three primary macronutrients, potassium helps plants grow strong cell walls, which in turn allows them to produce heavier yields. It also aids in efficient water use. Symptoms of potassium deficiency include weak growth and limp stems.


Chemical symbol: Si Silica (referred to in its elemental form as silicon) is a nonessential trace element. It helps plants create stronger plant cell structures that better support heavy fruits and flowers. It also helps your crops resist environmental stresses, pests and diseases.


Chemical symbol: Zn An essential micronutrient, zinc is important to plant enzymes and crop use of proteins. Symptoms of zinc deficiency include shorter stems and reduced growth and fruiting.
