Three part base nutrients are almost always split into Grow, Micro, Bloom bottles. Unlike two part grow & bloom sets, three part nutrients designed to work together for the plants entire growth cycle, adjusting the ratio or amount of each bottle you use depending on the plants growth cycle. With three bottle the micro minerals required by the plant have been separated and should be added to your feeding solution first and thoroughly mixed before adding the recommended amounts of grow and bloom nutrient. This will ensure maximum uptake of nutrients by your plants leading to healthy and more robust growth.
