I am new to the world of hydroponic gardening. I started about 2 months ago with the Emily's Garden hydrogarden, and I seem to be having a pH problem. I use vinegar to lower my pH. It works in the short term, but after a brief drop in my nutrient solution's pH, the pH climbs right back up to the 7.5 to 8 range, requiring more vinegar. It seems to be "stuck" in this range, if you will, and I am not sure what to do about it. My tap water is usually around 6 pH or so.
I use pre-mixed nutrient solution called Flora Nova by General Hydroponics. Will this alter the pH of my tap water?
Is vinegar an acceptable form of pH adjuster?
What should I do?
