My tap water has a high EC / PPM / CF. Do I need to take this into account when using Gold Range NUTRIENT?
With high EC / PPM / CF commonly know as hard water you most definitely need to take this into account when using Gold NUTRIENT. If your starting water is 0.4 EC / 200PPM / 4 CF or more then the use of a reverse osmosis machine to clean up your water is highly recommended, although not essential. If you have to use high EC / PPM / CF water then take into consideration the water value when making up your nutrients. The use of conductivity (EC / PPM / CF) and pH meters is highly recommended.
