These are 'daily values' for humans, not plants. Fertilizer percentages are by weight which greatly skews those percentages.
Here is a link to the nutritional value and with some simple math, you'll reach the same percentages that I originally quoted.

In regards to your 'quote from another forum', I was hoping for a link to a Schultz plant food product that verifies your statement above. Even if a few products are in-fact 'derived from molasses', I can promise you that they'll be of greater value to plants which doesn't mean you can get the same results using whatever molasses you guys buy.
At the end of the day, facts are facts and molasses simply doesn't contain the minerals or properties that contribute to 'fatter buds with more thc'.
