Will tomato food mircle gro work for greens like spinach? It has a 18 18 21 that might not be the best ratio for greens considering they need a higher N level. The medium will be soiless peat-based. Will the lime be enough Ca, there is none in the micro of mircle grow. Also, there is no sulfur in the MG micro, is that important? Again im using my own soiless mix that has no micro nutrients in it, only the lime.
Any help would be great. Thanks.
