Nor does it make your buds "sweeter", this is a common myth. People often equate what they feed the plant with what it will either taste like or, how "sugary" the bud will be. The truth is the plants do not convert complex carbohydrates in to even more complex carbohydrates in the flowers. There are some indirect benefits to feeding the soil with these products but they largely feed the microorganisms that live in the soil. This simply allows the plants to make more efficient use of the macro/micro nutrients that are either already present or, added as a amendment later. If the flowers did contain large amounts of these carbohydrates it would likely make it difficult, if not impossible to smoke. Anyone that has put a sweet, mollases-based BBQ sauces on their carefully prepared chicken,ribs etc. too early can easily make that association...it burns leaving a charred mess. Don't confuse natural resins (the carrier for THC and CBD's) with something you added that is sticky or sweet.
