I use humic acid called Grandman Enggy's. Can see here: https://advancednutrients.com/advancepedia/product.php?productID=30&catID=11

I use 30ml per gallon of this and 30ml per gallon of calcimax.

Foliar Applications
If used with foliar solutions, apply 3 to 6 ounces of TeraVita SP-90 per acre per application. The spray concentration should range between 1 ounce of SP-90 per 5 gallons of spray and 1 ounce of SP-90 per 100 gallons of spray. The optimal concentration is 1 ounce per 50 gallons of spray. When used in conjunction with any herbicide, insecticide, or fungicide, always use 1 ounce of SP-90 per 50 gallons of spray, regardless of the total spray volume used or the total amount of SP-90 that will be delivered per acre!


This is straight off of their product label (it's who we work with, and are VERY happy with the quality of their products). I have another humate usage guide, if you need further info.
