Hesi Coco Complex is THE supplement for flowering on coco substrates. Just like all the HESI supplements, Hesi Coco has been stabilized thanks to complex-binding substances and it is free of unnecessary ballast. Hesi Coco is not an A & B supplement, the A+B components are united in one bottle. Hesi Coco Complex contains both organic and mineral nitrogen. All trace elements have been stabilized in protecting complexes and have been enriched with vitamins and other vital elements both for the flowering. This way, a perfect balance is created in the system and a fast build up of a healthy micro-flora is achieved. It is possible that the EC of Hesi Coco is somewhat lower than other coco supplements because no salts have been added, since this would only raise the EC and these would be of no nutritional value to the plant (ballast).
