Are you sure you need calcium, or do you really only need magnesium. Should you only need magnesium, a quality magnesium sulfate (epsom salt) will really please your plants.

My pleasure. lol
lolI found where I got a problem. Too much Calcium in tap water. I will buy some Brita filter, its like RO/sistem.
Too much calcium in water blocks the access of magnesium, am I right?
And bought Epsom salt/magnesium sulfate MgSO4 32%. Half a tea spoon per 1 gallon for the first watering. Hope this help

Powdered dolomite lime (2:1 calcium / magnesium ratio) can be mixed in directly but it takes a while to break down and become available to the roots. To speed this up you can feed the lime to an aerated compost tea (slow brew with no molasses) and it will break it down for you quickly. Use epsoms if you need to increase Mg and not calcium as others have said.

They use it (hopefully) in a balance which is right for cannabis. I'm one who's not looking for any extra nitrogen, especially after a month or so of flower.
Maybe use organic calcium and magnesium salts such as citrate, gluconate, lactate, ascorbate, or the like.
Chelates/complexes often contain nitrogen which is, in the case of amino acid complexes, plant available (Mg bisglycinate contains 16% N & 14% Ca) whereas the N in EDTA and related chelates is not. But you'd need too high quantities of the latter to be healthy for your plants and that's why they're usually only used for micronutrients.
