these are critical purple auto in jungle growth soil mixed with about 25% native soil. I used a ph kit that you put the soil in, add some powder and water and shake. The PH came out OK. I checked the NPK and the N looked elevated (as far as I could tell with the kit)... I use water from my KOI pond to water. Iv stopped using Koi pond water as of now. Does this look like the beginnings of a N overload and if so is there anything to top dress to help it? thanks for your time.
