In addition to the many medical benefits of cannabinoids, cannabis also contains a plethora of healthy minerals and antioxidants. Whether you’re a grower, processor, or retailer, its important to know the full nutritional profile of your products. Cannabis nutrient testing provides an accurate profile of your growing mediums, source waters, inputs, and plant materials.

Modern Canna is regarded as Florida’s first and most reputable cannabis testing laboratory, and nutrient testing is one of the many analytical services we offer.

Cannabis Leaf Tissue Testing

Cannabis leaf tissue testing is the most common method for determining nutritional breakdown. The procedure is more formally known as foliar testing analysis and is a useful tool for managing the nutritional content of most plants, especially cannabis.

Foliar testing comprises of two areas: the routine analysis and diagnostic analysis.

Routine Analysis

Growers submit multiple samples over the course of a plant’s growth cycle in order to gauge its overall nutrient composition. This helps identify growth deficiencies before they become serious and irreversibly affect plant health. It should be done regularly (usually monthly).

Diagnostic Analysis

This process identifies nutritional deficiencies or the presence of toxins. Diagnostic analysis is primarily used as a corrective tool and has a greater degree of accuracy. Growers submit samples for diagnostic analysis when plants begin showing negative symptoms, such as yellowing of leaves.

Cannabis Nutrient Testing Is Shaping Cultivation Practices

Both routine and diagnostic analyses allow growers to develop their own cultivation strategy for optimizing nutrient and mineral yields. There is no singular method that works universally for every grower, not even when growers are based in the same geolocationand face near-identical climates.

It should be noted that each cultivar requires its own individual testing, especially if the plants are of varying age or have undergone different fertilization practices. Testing should also include control samples consisting of cultivars with no known deficiencies. While testing multiple samples repeatedly over an entire growth cycle can seem cumbersome, Modern Canna makes this procedure simple.

Testing Parameters for Source Water and Growing Mediums

Our laboratory also helps growers by testing source waters and growing mediums. Most cultivators agree that nutrient-rich water and soil typically produce larger yields and healthier plants. We are certified via EPA methodology to identify and quantify the following:

  • Macronutrients:
    • Magnesium (Mg)
    • Calcium (Ca)
    • Potassium (K)
    • Phosphorus (P)
    • Nitrogen (N)
  • Micronutrients:
    • Zinc (Zn)
    • Manganese (MN)
    • Iron (Fe)
    • Copper (Cu)
    • Boron (B)
    • Molybdenum (Mo)
    • Sodium (Na)
    • Nickel (Ni)
