It doesent sound right I suggest you to prior add fertilizers, you add first Ca and Mg till you get between 200-300ppm (scale 500) and then you fill the gap with nutes to desired EC for the needs of your plants. Doing this you can manage easier how much you need to add.

Damaged leaves I have a problem with one of the plants, the leaves are damaged and some of them had to be removed, the plant is growing too slow. I thought it is related to Cal/Mag but I've been adding it for a while since week 2 and the problem is not corrected
