This is a great discussion.

@MIMedGrower - I grow in containers. The soil test is a mix from all the containers I use. The excess soil from up potting and soil out of rotation are the sources of my soil I got tested. It all makes its way back into growing medium in >30 days. Either starts cuts clones VEG and flower. It all rotates in.

I guess my point was that I don't even think about pH until I see my test and then I don't think about it.

OK wait... how can I make my soil more acidic?


I only test new bags after mixing with perlite and sitting a few days and unless there is a problem never check ph again. I do monitor ec after i start fertilizing. I wasnt disagreeing with your method. I was just saying if you use added nutrients there are guidelines that work great for potting mixes. I didnt come up with them but they work well for me.

I dont know how to make soil more acidic. I guess more peat and less calcium would.

But why would you want to if your system works?
