sulfur

i have heard that my molasses should be unsulfured as to not kill microbes, but have also heard that microbes need sulfur and they say the plant needs sulfur so which is it sulfur good or sulfur bad? please help!

You want unsulphured molasses because the sulphurred version will acidify your media.

You can use these to add sulphur, good compost, Epsom salts (Magnesium sulphate) and potassium sulphate.

so its a ph thing only?

Plants need sulfur but there's different forms. Sulfured molasses will lower ph and it's not good for the microbes. It's made with sulfur dioxide which makes sulfuric acid when mixed with water.

Molasses and sulphurs do different things. The molasses is like a "carb load" to help fatten flowers, simply put. The sulphurs, my understanding, aids terpene production in general.

cool!

The molasses itself doesn't really fatten flowers. It mainly just feeds the microbes. It does have some other nutrients, mainly K. But the sulfur in sulfured molasses isn't the sulfur you want. Sulfur does help with terp production but there's better ways to add it like Nutty Skunk said. Magnesium sulfate, potassium sulfate, calcium sulfate, and langbeinite are all better sources of sulfur and doesn't mess with ph.
