The Hemp Goddess said:A pH of 5.8-6.0 is too low for soil grows. You are probably locking out nutrients that your plants need. Until you get your pH in line, nothing is going to help.
You generally need an RO or water treatment system of some kind. In addition, cartridge filters "do not open up space in the water". The water will take all the nutrients that we put into it. The reason that we want to start with water with a low ppm is so that you know what you are feeding your plants. The ppms in your water are basically "unknown nutrients". Since we want to know exactly what we are feeding our plants, it is nice to start with water with a low ppm.
