@liliarose, That's nice, that to you are interested 😍 all the growers have to, but not even half is interested about 😆
In the leaf between veins if its yellowing its sign of Mg, Mg is mobile and plant is able to take it from old leaves if she isn't able take it from the substrate via root. Ca isn't mobile
Ca and Mg almost always comes together
Always open it first, as tap water already containing it, so in case of CaMg it's easy to fit the water as a first giving elements to the solution, only if you are gonna open Si element, only in this case first open Si, and only Then CaMg , but i have heard that its better if u are deciding to give the substrate extra Si its better to give it with only with Si opened in the solution and give it inbetween of 1st and 2nd watering
Good luck in your grow 😍😍
