Know before you buy
You should apply this solution during the first two weeks of the flowering phase. This timing is critical to support the initial transition and promote vigorous flower site formation.
Optic Foliar SWITCH is designed for use as a foliar spray. You should apply it directly to the leaves to ensure efficient nutrient absorption during the early bloom stage.
No, this formula has an NPK ratio of 0-0.2-0.2, meaning it contains 0% nitrogen. It is specifically formulated to focus on phosphorus and potassium to drive bloom development rather than vegetative growth.
Yes, it is formulated for a wide range of flowering plants. Its primary purpose is to maximize blossom set and flower site formation during the transition into peak bloom.
This is a quick-release liquid concentrate. Because it is applied as a foliar spray, the nutrients are designed to be absorbed rapidly by the plant to provide immediate support during the critical early flowering window.
