    so maybe heading the wrong way by adding more.
    any thoughts pls

    sorry for hijacking some else thread.
    Mate - if those numbers are mg/l for calcium, then no, you do not need to be adding calmag for calcium purposes!

    No idea on the mag side of things, but spraying the plant with a weak Epsom foliar solution would sort that anyway.

    From what you’ve typed, they look like min/average/max...they are big numbers.

    Forgive me for tripping into this one but isn’t it just as easy to work out if you have soft or hard water with the use of just a ec meter 0.2-0.35, 0.4 is soft. And then the higher the read is hard. Or if you live where I do the reading is 0.0 in other words shit water!! Which def needs cal n mag added then again I ain’t no hamster doing rock climbing
