    it wouldnt hurt to have some. i use dolomiite lime the pulverized and i add it to the soil before hand and then topdress it 1 or 2 times a crop.

    Fox farm is a well balanced nutrient and already has cal/mag already in it. But, I always add crab shell to my potting mix to get slow release calcium. I then water with Epson salt the 2nd week of veg and then again the 2nd week of flower. Seems to work well.
