all you need to do is achieve balance... look at Albrecht's ratios...

the CaCO3 is a major controlling factor for ph, but its excess Mg that binds soils.

What I'm actually trying to achieve is to fix a fuckup I did when preping my soil. I forgot to add ground egshells in the compost i made and also forgot to add them to the mix I did. So I need to get some Ca in the soil since theres no supply of it inthere and my tap most likely doesn't have enough in it. So instead of buying stupidly expensive botteled Ca products I thought I'd go the powdered source way since its way cheaper. And my plants are already in their final pots :(
