When plants are in a vegetative state the Super Micro and Super Grow recipe is used. If you want a plant to be pushed into bloom, the Giant Bloom formula is added to the Super Micro and Super Grow recipe. By separating the formulas this way the grower can increase or decrease nitrogen (Super Grow) or phosphorus (Giant Bloom) as the plants demand without interfering with the micro-nutrients (Super Micro). This is how the professional greenhouse growers mix and match elements and compound for each stage of plant growth.
