Sorry, but this is not good information, especially for a new grower just learning. Maintaining the proper pH can be critical to the success or failure of a grow. Just take a look at our Infirmary forum and you'll see how many of the issues addressed in there are pH related. Yes, a properly amended organic soil can be self regulating but most new growers aren't going that route. They are using off-the-shelf products that often have a starting pH that is out of the desirable range for growing autos.
