I did mine with molasses 1tbl per litre in the last 2 watering of that flush for my OG Kush. They say that is can add weight and sweetness to the buds ,I did no comparable grow with molasses vs no molasses but from what I have read it breaks down in the soil and microbes send it easily to the plants roots causing a uptake of beneficial nutrients to the buds that may increase weight , taste more sweet and aroma but I have read a lot that says it ain't conclusive at all..hope that helps ya
