No I don't have any sites to back my claims but I have life experiences and if you have done any gardening in your life you learn that you cant grow every thing with the same soil. I have not had a lot of gardens mostly just grew a lot of weed. I have a pretty good garden now though I also have family who own a huge nursery and others who use to have an orchard and get a lot of info from them too. Most of the recipes you will find are suited to marijuana. Its like using miracle grow for all your vegetables. It will work good for most stuff but not all. One odd ball for example that would not work in this soil is my blueberry plants. They like a soil PH of around 5.5 and do not like a lit of nitrogen. Next year when I plant my garden I will divide the garden in to plants that like high nitrogen and plants that like high phosphorus. You can grow everything in the same soil and get OK results or grow to what your plants in the garden need and get good results. I wish I had a pic of my friends radishes for ya. It was TGA super soil recipe top dressed. His radishes were sad. Don't ever be afraid to start a debate with me I do not get mad
Its ok if some one disagrees or dose not believe me I have thick skin. I am giving the best advice I can based off of my life experiences and observations. Some times my info will be wrong so you should take every thing you read with a grain of salt and observe and learn on your own. No one you talk to hear will be rite 100% of the time.
