|I use John and Bobs and All in One. Since All in ONe is chemical, does it work at cross purposes with the John and Bobs?

|I think I would choose one product and use it alone, rather than in conjunction with the other - there's such a thing as too much of a good thing. John & Bob's Soil Optimizer is a concentrated soluble Humus along with important soil additives, including calcium. It should be just fine to use in your garden.
