CANNA COCO easy to use | CANNA Gardening USA
"Damage
Damage to crop caused by hard water Normally, PK13/14 and CANNA COCO nutrients can be used together. However, in case the tap water is very hard, this combination can cause problems. Very hard water contains high amounts of calcium and the amount of acid necessary to set the pH is relatively high. This is due to a high bicarbonate level in the water."
