Hi, so i'm using distilled water for my DWC, and I was wondering if it was normal that, while following the Advanced Nutrient formula calculator on their website, using a reservoir filled up with 26 L of distilled water, they expected me to reach 800 PPM, and im at 260 PPM ? The nutes are 3 part formula Micro-Grow-Bloom from AN
Different ppm tester manufacturers calculate ppms differently. Some use a EC x 50% calculation and others at .64 or .70. Also ensure u have calibrated ur meter
