I just got done watching this DGC clip Optimal Nutrieent PPM for Cannabis Plants and am confused. I thought the PPM was a measure of dissolved solids (salt mostly?) in your water/nutrient mix. I don’t understand why one would want it so high (800-1200 ppm) or how to get it that high if following the nutrient schedule results in water that test lower?
