Like others have said, coco is inert so you have to feed every time. pH to around 5.8-6.2 is a good starting point. I water til theres 10-20% runoff everytime also. Coco is easy, dont sweat it. If I can do it, you definitely can
I hear ya on that! I went back to pH drops and these 0.5 resolution pH strips for when I need to test pH.
Most people who have pH meters don't calibrate them nearly as often as they need to be, and I was one of those people, so using drops or strips that are properly stored makes me feel a lot better about the readings I get.
My city tap has been 7.1 for the last ten years. Twenty drops of pH down per 5gal bucket . Gets me to 6-6.2. guess at this point I really don't need one but I still check and nothing has wavered. Guess I'm pretty lucky
I never ph anything but am very happy with the Oakton EcoTestr pH 2+ Pocket pH Meter. I have had it for years, I store it dry and when I use it I check it. Only had to recalibrate it once. I would recommend it to anyone, Best bang for your buck in my opinion
