ok guys i got some ph indicator (iodine) and wondering instead of testing loads of small smaples of my nut' water could i not just place sum in the nutrient feed tank and add normal water to get it to the right ph? so basicly the whole nutrient tan would be ph indicated....would the iodine harm the plants?
