Molasses is valuable for feeding beneficial microbes, specifically beneficial bacteria. It is not really a plant food, you don't use it to feed plants, you use it to feed the bacteria that feed your plants, the bacteria in turn breaks down raw elements in your soil into a usable form for the plants to use.
However, the claim that molasses should be used to "get Stronger smelling buds" is somewhat misleading, as this would only be true if your soil was so devoid of beneficial bacteria that your plant was unable to uptake the nutrients it needs in sufficient quantities during flowering, this is unlikely. Most soil, if you are growing organically, has sufficient populations of bacteria to facilitate this process, the molasses simply adds a boost. And, if you are using chemical fertilizers the discussion is moot as chemical fertilizers do not rely on microbial activity, similarly chelated organic fertilizers don't require microbes to break down raw elements into a usable form.
Molasses is really useful for making teas, or other processes that are used to break down raw amendments into food for your plants. Keep in mind however that molasses feeds bacteria, but not fungi, so if you are trying to increase the mycorrhizal activity in your soil, molasses will not help.
Hopefully, this doesn't come off as too discouraging. Molasses can be a helpful tool in organic growing, but unfortunately, many online sources have latched onto it and promote molasses as some kind of household item that is a cure-all organic amendment, which it is not in my opinion. It is useful in organic gardening, but it is unlikely that if your buds weren't as smelly as they could be that molasses is what is missing.
I call that claim misleading.
