Nik from Rooted Leaf Nutrients (use code GROWCAST for 20% off) is BACK for another installment of his nutrient deep dive – this time focusing on phosphorous and magnesium. Nik shares his beliefs around the myth of the PK booster, and why phosphorous has been mislabeled as a nutrient that should be overapplied during the flowering stage. Nik instead encourages to think more about the relationship between MAGNESIUM and phosphorous, tracing these minerals all the way back to the very beginning of the photosynthetic process- where magnesium helps capture energy from light and transfers into the tri-phosphate bond known as ATP. Nik extrapolates on what this means to us cannabis growers, and how we can maximize our plants biomass production when we full understand the link between magnesium, phosphorous, and light intensity.
