I am a new grower and haven't even begun the entire growing process yet but I seem to have a misunderstanding of what I need to do when it comes to feeding my plant. I can't seem to tell if I need to use other fertilizers alongside an organic medium or if the medium doesn't matter and I have to use synthetic fertilizers as well. I don't want to "double up" my feeding by giving it synthetic fertilizers if I don't have to. if I don't need to use synthetic fertilizers what are some good organic mediums that i can use?
