Is possible to have hard water but water may be lacking calcium, or maybe has calcium, and lacking magnesium.Water hardness test's don't tell you which may be lacking.(local water report might)
I have plenty of calcium, and little to no magnesium in my water and so I decided to try adding a little Epsom salt (magnesium) when i dose other nutrient's and plant's that were doing poorly,improved.
Seachem's Equilibrium might also produce result's.
