Al's 5:1:1 mix pH questions
Mixed about 20 of my containers to that mix but I did them pot by pot so I erred on the side of less lime per bucket of mix I made. After an hour or so I checked the pH and some of them are reading 5-5 1/2. Does it take 24-48 hours for the lime to register differently on pH meters? Perhaps I added too little? At this stage what's the easiest and safest way to bump them up to 6 or 6 1/2? Thanks.
