The calmag is not 100% organic but it is very close and essentially it will be all gone by the end of flowering as for the LK it is organic and the only bottled fertilizer I still use, I would pay big money for the recipe but then again I've had success without it.
Using dolomite lime if you have regular ph water will take care of both cal and mag but calmag is an awesome product and is the best choice in a pinch in say flowering.
