Thank for the input but I sorry to disagre but logic tells me otherwise.
The manufactures make nute solutions for both soft & hard water.
By doing this they must find the average disolved salt levels for both soft and hard waters and then make thier formulas to suit the average soft water and hard water.
Therfore I took what I consider to be an average soft water salt level for soft water to be about EC.0.4-0.5
Therefore I took my EC. 0.1 water and added Ca & Mg In equal parts until an EC of 0.4-0.5 is atained.
I have written to canna and GHE on the subject.
We shall see what they have to say.:thumbsup:
