Molasses does very little for the plant it's self, molasses feeds the micro-beasties in the soil and helps keep it alive. Keep those micro-beasties feeding, farting and fucking, that's the trick to yummy buds.
The thinking that adding sugars will make your buds fat and sweet is not true. Many think this way and add way to much molasses and screw up their plants. TBL spoon per gallon every week is fine. I add 12oz to my 32 gallons (2 tea spoons per gallon) teas and feed with that once a week. Just keep that soil rich and healthy and alive, that's how you get them BIG FAT BUDS!
Good Luck
