I wrote a post where I apologized for speaking so harshly and that I might be wrong. A bit of molasses in water may be a good thing for soil microbes.
Emilya seems to think so, and she grows better bud than I do

I'm not sure I can apologize for assholosity in consecutive posts, so take my word for it. I may have spoken with authority when I meant concern.
I, personally, am not comfortable feeding molasses in water to plants in flower because it can potentially disrupt a soil community/soil food web that has organized iself around assisting your flowering girl to extract nutrients from the soil. Why mess with a working system - and I just have to trust that soil organisms know their business better than I do.
What to do in late flower is an area that seems to support lots of myths and theories - since bud size and quality is so important to what we do.
Myth of 'The Flush' - this is the idea that pouring extra water through the soil somehow rinses chemical flavors out of the plant. I have not done empirical tests to prove this is a myth, but it makes no sense to me that washing 'junk'and nutrition out of the soil washes 'junk' out of the plant. - On the other hand, washing 'junk' off the OUTSIDE of the buds at harvest time does rinse off harsh flavors from hair, dust, insects and the miscellaneous stuff that clings to sticky trichomes.
In my semi-humble opinion, molasses providing sweetness to buds is a similar myth. If buds needed more sugar they would take it from storage in the leaves, stalk and roots and keep their leaves green to keep transforming light into sugar (and H2O and CO2 into O2, and ATP into ADP, and other stuff I barely understand since I got my high school chemistry teacher fired and had to drop the class.) But instead they often let the leaves yellow, apparently becaus ethey need the nitrogen in the leaves to build buds more than they need the nitrogen in the chloroplasts of the leaves to keep synthesizing more sugars.
Feel free to correct me. I sure don't want to lead anyone astray.
