Routine vs. Diagnostic Leaf Tissue Analysis for Cannabis
Features - Nutrient Matters
Tissue testing can tell you if your nutrient program is on target and is one of the best methods for diagnosing nutrient-related disorders.

Foliar tissue analysis is an extremely useful tool for growers managing plant nutrition of cannabis. It falls into two major categories: routine analysis and diagnostic analysis. Routine analysis is for problem prevention, whereas diagnostic analysis is for problem solving.
The routine analysis allows growers to monitor nutrient uptake in the plant during production. This requires a grower to take multiple samples over the entire course of the growing season to identify problems or issues before they become serious concerns.
Growers can use diagnostic analysis to diagnose deficient or toxic nutrients when the plants are displaying negative symptoms. This process helps identify the specific problem and is primarily a corrective tool. Plant tissue analysis is especially useful in determining micronutrient levels in the plant and has a greater level of accuracy than a substrate test using a water-based extraction.
Tissue Analysis Strategies for Cannabis Growers
Routine analysis sampling is a general management tool when the plant is displaying no negative symptoms. The strategy here is to determine the nutrient status of the plant by plotting tissue values over time to ensure that a fertility program is on track.
