Does pH change over time?

You are missing the point. A good buffered soil will handle all you put in it.

Read the following from a RIUer who explains it well. It does not matter (within reason) the pH of what you put in, nor what runs out. The soil itself will buffer the soil solution to a perfect pH

Another pot forum myth.... Do some research, starting with some of the links I or AImAim provided you with.

There is a reason companies like Premier (Pro-Mix) etc.. add dolomite lime to peat based container mixes, to help stabilize pH and buffer pH over the course of a container grow. Also EWC is a great natural buffer as well because of all the humic acid is naturally provides, which again, help the mix buffer pH levels.

Bottom line......check it.

Unless your fingers have built in test strips or something LMAO

So in my next grow if I use lime in the soil it will help me maintain a more neutral level if I under and or over pH what I put in?
