High CBD plants generally want less nitrogen during flower than the THC heavy strains most nutrient charts are written for. Overfeeding shows up as dark clawing leaves and a harsh taste after cure. I dialed back to about two thirds of the bottle recommendation after reading the feeding schedule notes on https://calmcbdseeds.com, which mention that many CBD lines descend from fibre hemp with modest nutrient demands. The plants finished cleaner and the flower burned smoother, so I am sticking with it.
