Yeah I used it. I seemed to notice a little fattening of the buds when I used it. I used it in flowering.
Add molasses to your plain water every other time. Don't add it to your water with nutes.
Use 1 tbsp/gal. (works out to roughly 1/4 tbsp / liter)
Only use in soil, don't use in hydro.
Use Blackstrap unsulphured molasses.
The molasses has some nice micronutrients in it.
