The humic acid is probably the powder, it should dissolve in water and make a solid black solution. If that is the case then the other stuff would be the kelp. If it is fresh cut kelp then it won't dissolve in water at all. However, it could be some kind of kelp extract in which case it probably would be soluble in water. It's kind of important to know so that you know how much to apply. If it was regular powdered humic acid you could use a teaspoon to a tablespoon to a gallon of water (some places recommend making a concentrate with the powder and then using an ounce of the concentrate per gallon).
The kelp, if it's regular cut kelp, you would also use up to a tablespoon per gallon for AACT, or mixing into soil before transplant, or top-dressing. But if it is some kind of kelp extract the dosages would be much less, like half to a teaspoon per gallon.
Did these actually come pre-mixed together? A photo might help.
