You could potentially mix and spray TurfGrass Pro Micros and Hydra-Hume at the same time. We would recommend a small jar test for compatability before mixing a large tank for the first time. You could also use MicroMerge, which is basically HydraHume impregnated with micronutrients all in one product.
