N-P-K Their roles in the life cycle of marijuana and how it pertains to my feeding schedule. I'm going to paste a few descriptions of what N-P-K are used for in a plants life cycle and compare it to my nutrient line. (General Hydroponics 3 part Flora series.) Nitrogen Nitrogen is primarily responsible for vegetative growth. Nitrogen assimilation into amino acids is the building block for protein in the plant. It is a component of chlorophyll and is required for several enzyme reactions. Phosphorus Phosphorus is a major component in plant DNA and RNA. Phosphorus is also critical in root development, crop maturity and seed production. Potassium The role of potassium in the plant is indirect, meaning that it does not make up any plant part. Potassium is required for the activation of over 80 enzymes throughout the plant. It's important for a plant's ability to withstand extreme cold and hot temperatures, drought and pests. Potassium increases water use efficiency and transforms sugars to starch in the grain-filling process. Flora Grow: 2-1-6 (why would the grow hold the majority of K?) Flora Micro: 5-0-1 (notice the micro holds the majority of N.) Flora Bloom: 0-5-4 (the bloom looks to be ok) During veg their feeding schedule calls for 12.5 ml grow, 7.5 ml micro, 5 ml bloom per gallon of water. During bloom their feeding schedule calls for 5 ml grow, 10 ml micro, 15 ml bloom per gallon of water. Why are they calling for so much N during the bloom phase ? I'm looking to phase out the N during the last month or so of bloom. Any suggestions are welcome.
