SaleHesi Bloom Complex is an organo-mineral bloom stimulator containing both the classic nutrients — nitrogen, phosphorus, potassium and calcium — and vitamins and amino acids, giving the plant everything it needs for a healthy, abundant flowering. It includes a pH corrector that brings the water to a slight acidity, optimal for nutrient uptake. Bloom Complex contains no spurious molecules or elements, and its trace elements are stabilised in organic complexes for uptake across all pH ranges. It also contains two types of nitrogen, mineral and organic — which is why EC should not be used to dose HESI products. Avoid overdosing.
