reviewing the water quality report
I just checked out my local water characteristics here (http://www.nyc.gov/html/dep/pdf/wsstate12.pdf, page 10) for the first time ever. Wondering if I need to modify the potting mix recipes or fertilizer program (currently Foliage-Pro exclusively) in any way.
Our water is a bit too alkaline for plants (pH 6.7 to 9.2 with 7.2 average). BUT alkalinity is within the acceptable range at 11.2-19.3 mg/L CaCO3 with 14.8 average. Because alkalinity is low, I understand high pH does not matter and should not compel me to do anything differently in the soil mix or the fertilizer. Right?
Should I pay attention to any other metrics?
