Ok let start by saying this is my first grow and first time ive mixed soil also im on a budget. So this is what i have to work with so far: sphagnum peat moss, perlite, steamed bone meal, worm castings(also started a farm of Eisenia fetida),Blood meal,and Azomite. I have epsom salt and diatomaceous earth lying around I plan on using the Dia earth in spray should i add some to the soil also and your thoughts on epsom's in the soil?? Thanks for reading this and helping me!
