NPK in vegetative, growth stage: 160/30/175 mg L
NPK in flowering stage: 160/60/60 mg L
Here's a roundup of recent research done expressly on medical THC cannabis. Wondering how to interpret the recommendations?
For instance, is a NPK of 160/30/175 mg L equal to 10/2/12?
Does 160/60/60 equal 10/4/4?
I'm posting a list of links to NPK research by Nirit Bernstein, from the Institute of Soil, Water and Environmental Sciences, Volcani Center, Israel.
Medical Cannabis recommended N, P, K levels from Volcani Center research:
N veg: Response of Medical Cannabis to Nitrogen Supply Under Long Photoperiod (2020)
P veg: Response of medical cannabis genotypes to P supply under long photoperiod: Functional phenotyping and the ionome (2021)
K veg: Response of Medical Cannabis Genotypes to K Supply Under Long Photoperiod (2019)
N flower: Nitrogen supply affects cannabinoid and terpenoid profile in medical cannabis ( Flowering phase 2021)
P flower: The Highs and Lows of P Supply in Medical Cannabis: Effects on Cannabinoids, the Ionome, and Morpho-Physiology (2021)
K flower: Effect of Potassium (K) Supply on Cannabinoids, Terpenoids and Plant Function in Medical Cannabis (2022)
