I am confused with my water quality in my area. I grow both orchids and nepenthes in my greenhouse so I got my water report for my area from my local water authority. The report says that a) Turbidity = 0.22 NTU, b) pH = 7.91,
c) Chlorine Residual = 0.91 mg/L (ppm), d) Hardness = 33 mg/L or 1.93 gpg (grains per gallon), e) Arsenic = 0.173 ug/L (ppb). (mg/L = ppm)
If my hardness is 33 mg/L or 1.93 gpg = soft, why do I get mineral deposit on the leaves of my plants? I water with RO but my mister and swamp cooler is Tap. Also, I get lots of mineral crystals on my swamp cooler. They did not give me the TDS but it is said that TDS and hardness is almost same. I don't use a water softener. Is this possible?
