"Sweeten up the buds" I think this is a misnomer. You
can strengthen or enhance, even increase the natural terps by the use of S and Mg.....Carbs do nothing (for taste/bud size) and you must realize that even unsulfured molasses,,,,still has S in it. Just reduced to remove the unwanted smell/flavor it has......Some more of the "molasses" at finish myth explained.....It may help taste a bit in some strains but, sweeter - nah!
Yeah, I've been real stressed lately. Impatient and crabby. It should not be expressed here but, sometimes I slip.
