Hello again....if I may......hope this helps. Also, my review on Prescription Blend is pretty thorough in regards to whats in it and where its sourced. It's in my sig. Here's a text excerpt below the pics
Bio-Si: Mixed first, used in all developmental stages except seedling
A silica complex liquid innoculant with plant derived organic/non-GMO amino acids made from multiple silica sources. Silica sources include rice hulls, but not just any old rice hull. Rice hulls that have been harvested after the plant has naturally accumulated this element from their environment with potassium silicate. Helping to increase stem strength to support heavy flower, it is designed to work with Pre-Cursor as they provide resistance to environmental issues such as heat and water stress. A broad and diverse spectrum of naturally occurring and beneficial microbes pack punches of both Nitrogen and Potassium while increasing cell wall rigidity.
CORE A: Mixed second, used in all developmental stages
Specifically optimized for medical gardens, an amino acid micronutrient complex that encourages cell division and rapid growth. Its cornucopia of cannabis goodness drives enzyme function to store and transport energy. Combining macronutrients Phosphorus, Potassium, Sulfur, and Magnesium along with a plethora of fully chelated micronutrients, the variety of components naturally supports plants biological signalling in both flower set and root growth. Designed to work with CORE B.
CORE B: Mixed third, used in all developmental stages
A highly absorbable Nitrogen profile that allows plants to orient to capture light while building plant tissues. Nitrogen, Potassium and Calcium combine to provide all macro and micronutrients needed throughout an entire life cycle. Aids in creating building blocks for oils and terpenes. Allows for lush vibrant vegetative stages and increased flower mass.
Big Data: Mixed fourth, used only in flower stage
Changing the NPK ratio, it is a phosphorus and potassium supplement. Used in flowering, it is fully optimized for the needs of fast-growing gardens, (and works exceptionally well with auto-flowers for this very reason). It increases sugar production, aids in flower formation and supports fundamental enzyme function in flowering plants.
Kelpful: Mixed fifth, used in all developmental stages except seedling
Its combination of several varieties from the North Atlantic and Tasmanian islands are some of the world’s most prolific species. They are chock full of organic fulvic acids that support rapid recovery from transplant shock. The kelp is cold pressed to preserve its naturally active plant material components
Pre-Cursor: Mixed last, used in all developmental stages except seedling
A top-of-the-line metabolic booster that feeds root zone microorganisms. It accelerates plants jasmonic acid biological pathway. A Calcium, Magnesium and Phosphate supplement that can easily be used as an additional Cal-Mag supplement in and of itself when mixed separately
