Are you growing in soil?Are you organic growing?A very minimal amount of what's contained in the molasses is actually absorbed by the plant. The sugar/carbs youre adding are actually used by the microherd contained within the plants rhizosphere which in turn give nutrients back to the plant in a symbiotic relationship. In 1litre I wouldn't add more than 1tsp due to too much molasses hindering the uptake of nitrogen. J
