First time grower. I’ve been sticking to a lite feeding Canna coco schedule and the plants seem happy. My local tap water has a pH of 6.3 so I’ve been letting it sit for 48 hrs before mixing the nutrients to avoid some of the inherited chlorine. I prepared the Bliss coco coir by rinsing out the coco and soaking it with cal-mag for 8 hrs twice before transplanting Mephisto’s Fantasmo Express and Chemdogging strains. My question is, do I need to add cal-mag to the nutrients? If I do need to add calcium could I use the NFTG Herculean harvest and Bloom Khaos as a foliar?
