5-1-1 and ph
Here's my quandary and question.
I made 50-60 gallons of a modified 5-1-1 this year. The modification was 1 and 1/2 parts turface and 1/2 part potting mix replaced the peat component. Everything else remained the same.
Here's the issue. The lime is supposed to balance out ph and supply Ca and Mg, right? Well, my municipal water is basic. So, what may be a balanced ph at the beginning would probably be more and more basic as the season progresses, no?
Should I be adding a quick acting gypsum if I'm shooting for a ph slightly on the ACIDIC side. I have some of this stuff for my "dirt" garden. Should I add a tad to my containers also?
Here is a link that might be useful: fast acting gypsum
