I'd call molasses more of a soil additive than a fertilizer and there are grows that do not benefit from using it. While it works very well mixed into the soil, Bone Meal and other solid, organic ferts can also be made into a tea for fertilizing. In addition to the Bone Meal, you should use some of the Blood Meal for more Nitrogen. You'll also need to find a source of Potassium as that is the primary flowering nutrient.
All soil benefits from molasses by stimulating beneficial microbial activity, promoting chelation, and allowing the plant to uptake required nutrients. What grows would not benefit is a hard one to imagine.
Blood and bone meal can be dangerous products as they are derived from ground up diseased carcasses and meat packing scraps, including brain and spinal tissues. Don't breathe any in, if you insist on using it.
You can achieve a greener plant by pushing a rusting nail into the soil for slow release iron.
You can blender a banana peel with your tea, or the water you make your tea with, and strain for potassium. Sometimes I just mix in a chopped up banana peel in my soil.
