Towards the end of the flowering and fruiting phase nutrient intake slows down, yet there are considerable reserves of nutrients left in the plant sap. If these levels are depleted during the final development of the fruit before harvest the resulting crop will have a bitter metallic taste.
The term flushing can be misleading; a better term would be finishing since it is essential that any nutrients not used by the plant are removed before harvest. This is exactly what biOpOnic Flush does by supplying the correct ratio of enzymes, organic plant hormones, and catalysts to enable your plants to process as much of the excess nutrient as possible and remove any surplus prior to harvest.
