Note. Molasses is what you want to use, if you are growing organic. It is not going to do much for a bottled nutrient regime. The purpose of the molasses is to feed your microbrial life in your soil and the little microbes will make the nutrients more readily available to your plants. The nutrients as in the nutrients in your soil like compost, bone meal, kelp meal...not bottled nutes. The microbes will eat up the nutrients and poop and die and make babies if they are given the right environment to thrive. That is why most growers use molasses to make teas, you can pump a bunch of air into the resevoir with compost and molasses and water with a microbe rich tea, not a nutrient tea...it helps your nutrients become more available.
So, adding molasses with water to your soil will probably help create more microbrial life and could give your plants a boost...if your soil has good stuff in it. But making a tea with the correct ratios of compost and molasses with the correct amount of air would give you even more microbe life, with good compost of course. Not growing organic, maybe wasting your time with carbohydrates for your microbe life.
