Cannabis Fertilizer Tips & Programs
A nutritional program that maximizes productivity begins with the right growing media. Start with a well-aerated and porous soil with a pH between 6 – 6.2 and an EC between 1 – 1.5 mmhos/cm. Routine monitoring of the pH and EC is highly recommended. Adjustments to fertilizer rates will be based on plant age, growth phase, water test analysis, temperature, humidity, pH/EC monitoring, and other factors.
To ensure effective propagation, dip cuttings into Stim-Root® Rooting Hormone prior to planting to increase the number, quality and uniformity of roots per cutting. This proprietary rooting hormone is registered under the CFIA Fertilizers Act.
Seedling Germination and Starting (week 1)
Apply Plant-Prod MJ™ Boost at 0.5 g per 1 litre (75 ppm N) once or twice to ensure adequate phosphorous levels. This will provide a good initial boost to the roots.
Vegetative Growth (week 2-3)
Lighting during this phase is generally 18-24 hours. Fertilize with Plant-Prod MJ™ Grow at 0.8 – 1.2 g per 1 litre (100-150 ppm N) on a constant feeding schedule.
If EC levels drop below 1, increase the feed to 200 ppm N. Monitor EC and pH during the full crop cycle.
Rotation with Plant-Prod MJ™ Cal Kick every second feeding is recommended. The requirement for this supplement should be determined by water sample results, provided by your Plant-Prod sales representative.
Bud Set (week 4)
Lighting should be switched to 12 hours on, and 12 hours dark. In order to help the plants set buds, or when the buds are pea sized, feed once or twice with Plant-Prod MJ™ Boost at 1 g per 1 litre (150 ppm N). Continue rotation with Plant-Prod MJ™ Cal Kick as needed.
Bud Sizing (week 5-10)
Lighting should continue at 12 hours on, and 12 hours dark. Begin continuous feeding with Plant-Prod MJ™ Bloom at 1 – 1.5 g per 1 litre (100-150 ppm N). This will encourage full bud set and enhance bud filling. Continue rotation with Plant-Prod MJ™ Cal Kick as needed.
Finishing (week 11-14)
Plant-Prod MJ™ Finisher will help with plant finishing when applied at 0.65 g per 1 litre (25 ppm N, 200 ppm P2O5). The higher phosphorous and potassium will benefit the plants in their reproductive stage through to finishing. Switch to clear water 14 days before harvest.
Any Stage (week 1-14)
Plant-Prod MJ™ Spike (CaMg) can be used throughout the production cycle in conjunction with any Plant-Prod MJTM formulation, mixed in a separate tank. This completely chelated formulation of calcium (Ca) and magnesium (Mg) in a 2:1 ratio avoids the risk of interfering with bud formation, setting and sizing. Rate should be determined by water sample results. Consult your Plant-Prod sales representative for proper use.
