I just cheked the official analysis of the tap water here. It is 100 mg Ca/L. So when watering, my plant always get 50-150 mg Ca. The carbonate hardness is odH 18 and total harnedd is odH 23
Is that enough for the plants life cycle?
Could use of calmag result in overdosing Ca, resulting in some kind of mineral lockout?
Maybe I just shuold add Mg sol'n to my water only? Mg content is in the range 20-30 mg/L.

Sulphate content is between 30 and 110 mg/L, depending on where in the city the sample is taken.

I will find out presicely which source I get my water from. Then I can list ion contents of my particular tap water.

Enjoy Sunday - here the sun is shining. The balcony calls on me for gardening. Got tomatos and strawberry plants yesterday.
