Cannabis Nutrient Management Course

Lesson 1 • The Role of Water in Nutrient Delivery

Examines water quality parameters and their direct effect on nutrient availability. Students learn to evaluate source water before building any feed program.

Lesson 2 • Plant Physiology and Nutrient Uptake

Explains root anatomy, active and passive uptake mechanisms, and the cation exchange process. Links cellular biology to practical feeding decisions.

Lesson 3 • Introduction to Growing Media

Surveys soil, soilless, and hydroponic substrates and how each affects nutrient dynamics. Sets the context for media-specific feeding strategies covered later.

Lesson 1 • Measuring and Monitoring pH

Covers pH meter calibration, probe maintenance, and runoff testing procedures. Accurate measurement is the prerequisite for all corrective action.

Lesson 2 • Media-Specific pH Management

Addresses how soil, coco, and hydroponic systems each require different pH targets and correction strategies. Reinforces media knowledge from Chapter 1.

Lesson 3 • pH Science and the Availability Chart

Explains the pH scale, ion solubility curves, and the classic nutrient availability chart. Connects pH theory to visible plant outcomes.

Lesson 1 • Diagnosing Macronutrient Deficiencies

Trains systematic visual diagnosis of N, P, and K deficiencies using symptom patterns and mobility rules. Connects diagnosis to corrective feeding actions.

Lesson 2 • Nitrogen: Functions and Management

Covers nitrogen's role in chlorophyll and protein synthesis, uptake forms, and stage-specific demand. Students learn to balance vegetative growth without excess.

Lesson 3 • Potassium: Functions and Management

Details potassium's role in stomatal regulation, enzyme activation, and resin production. Students learn to adjust K levels during late flowering.

Lesson 4 • NPK Ratios Across Growth Stages

Synthesizes N, P, and K management into stage-specific ratio frameworks for seedling, veg, and bloom phases. Students build a complete NPK schedule.

Lesson 1 • Diagnosing Secondary and Micro Deficiencies

Applies mobility rules and visual patterns to distinguish secondary and micronutrient deficiencies from each other and from pH issues. Builds diagnostic confidence.

Lesson 2 • Iron, Manganese, and Zinc

Details the functions and deficiency symptoms of Fe, Mn, and Zn, which are the most commonly deficient micronutrients in cannabis. Covers chelation and pH sensitivity.

Lesson 3 • Calcium and Magnesium Management

Covers Ca and Mg roles in cell wall integrity, chlorophyll, and enzyme function, plus their antagonistic relationship. Students learn Cal-Mag supplementation strategies.

Lesson 4 • Sulfur and Its Crop Importance

Explains sulfur's role in amino acid synthesis, terpene production, and enzyme activation. Addresses sulfur deficiency patterns and common sulfur sources.

Lesson 1 • Understanding Fertiliser Labels and Guarantees

Decodes guaranteed analysis labels, elemental vs. oxide notation, and solubility data. Accurate label reading is the foundation of precise formulation.

Lesson 2 • Mixing Order and Compatibility

Explains why mixing order prevents precipitation and how to identify incompatible salt combinations. Students follow a safe mixing sequence for complex solutions.

Lesson 3 • Calculating Nutrient Concentrations

Covers ppm, mg/L, and mEq calculations for building target nutrient profiles. Students practice dose math for both stock solutions and direct mixing.

Lesson 4 • EC Targets and Solution Verification

Links electrical conductivity to total dissolved solids and nutrient load. Students set EC targets by growth stage and verify solutions before application.

Lesson 1 • Vegetative Stage Feed Design

Builds a nitrogen-forward vegetative feed program with progressive EC ramp-up. Students learn to match feed intensity to canopy development rate.

Lesson 2 • Transition and Early Bloom Nutrition

Addresses the nutrient shift during photoperiod transition, including nitrogen reduction and phosphorus elevation. Students manage the stretch phase without deficiency.

Lesson 3 • Peak and Late Bloom Nutrition

Covers high-demand peak bloom feeding and the strategic late-flower nutrient reduction leading to flush. Students balance yield and quality through final weeks.

Lesson 4 • Seedling and Clone Nutrition

Covers the minimal nutrient needs of seedlings and clones and the risk of overfeeding at this stage. Students design a gentle starter feed program.

Lesson 1 • NFT and Ebb-and-Flow Systems

Examines nutrient film technique and flood-and-drain dynamics, including solution recirculation and salt accumulation risks. Students troubleshoot common system failures.

Lesson 2 • Comparing Systems for Nutrient Efficiency

Evaluates nutrient use efficiency, waste output, and scalability across all covered systems. Students select the optimal system for a given production goal.

Lesson 3 • Coco Coir Nutrient Management

Addresses coco's unique cation exchange behaviour, high-frequency fertigation, and calcium buffering requirements. Students design a coco-specific feed schedule.

Lesson 4 • Soil-Based Nutrient Management

Covers living soil nutrition, organic amendment scheduling, and the role of microbial communities in nutrient cycling. Students build a soil-based feed program.

Lesson 1 • Tissue Testing and Interpretation

Covers sampling protocols, laboratory submission procedures, and interpretation of tissue test reports. Students translate lab data into actionable feed adjustments.

Lesson 2 • Identifying and Correcting Nutrient Toxicity

Covers visual and analytical identification of nutrient toxicity, including salt burn and specific element excess. Students execute corrective flush and reset protocols.

Lesson 3 • Optimising for Yield and Quality Metrics

Integrates nutrition data with yield weight, cannabinoid, and terpene outcomes to refine programmes. Students build an optimisation feedback loop across multiple cycles.

Lesson 4 • Runoff and Leachate Analysis

Teaches runoff EC and pH tracking as a real-time indicator of root zone salt accumulation. Students use leachate data to prevent toxicity and lockout.
