I would love to stop using calmag+ altogether but I guess not only am I a creature of habit I also want my plants to stay happy & healthy. They are so green that I'm skeptical of changing my routine. I have to ask what kind of water source do you use?
It's my understanding that if you use water sources that do not contain macros like RO or distilled then you also need a soluble form of cal/mag to help absorb the other nutrients from the soil. I amend with gypsum, D-lime, and crushed oyster shell among other things to my recycling mix plus add eggshells to the EWC from my worm bin. Am I overkilling it? I ask because I'm getting to the end of a bottle and don't want to order it again if I don't have to.
