Firstly, I've never even heard of the shit. Sounds interesting. Wouldn't hurt to try, as I don't think it would be harmful. Maybe mix in 5ML per gallon of water to start and see how the plants do(every other watering). Full dose would be one tablespoon (15ML). This is just personal choice, but I don't like to use molasses until the final two weeks of flowering, though there's nothing wrong with starting during veg.
