you should ammend your soil with something like perlite. cannabis, likes loose, airy soil. not compact soil that holds too much water. this will suffocate the roots and not give you optimal performance. there is nothing wrong with your choice of soil (although it's far from ideal, it will work. it's where i started.). you should be able to find a good organic soil at a local hydroponics store, or actual gardening store. i found roots organics soil in my area for $13 per 1.5 cu. ft. bag.

nice pics by the way!
