@Madsativa: how do I use them? Im not sure exactly what the pH of my soil is. I got a good deal on some basic potting soil at the hardware store, so I added some perlite to it and viola! It doesnt mention what the pH levels of the soil are though...but I can tell that it is alkaline after the lockout problems I am having. How can I test the pH of the soil before I even use it?
