Nutrition to start Flower ? featuring molasses and light

Molasses is kind of an end-of-flower kind of thing. You should encourage the plant to produce its own sugars right now so that it can feed the microbes and help metabolize new nutrients to the plant roots. You could do some I guess but. If you are doing organic fertilizers you can do a top dress pretty much whenever it kind of hard to over due. But if feeding bottled nutrients, follow the schedule,and depending on the size of the plant you may need to adjust their recommendations to less or even more if it is big.
