Humic acid is a soil conditioner and not a plant nutrient. 1/4 teaspoon per gallon of water 3 times per year is plenty. Do not spray it on the plants, it can clog pores and provide a substrate for fungi to grow in. If you did spray it on your plants and it is not going to rain for awhile I would rinse them off.
