Yes super thrive works , Only use 1/4 tsp (teaspoon) per gallon a max ,once or twice during the vegetative cycle of the plant, Never during flowering. Super thrive will delay flowering a super long time, by weeks or months, not in a good way either. If given in to high of dose age it will cause mutations in the plant . Yes you can give a plant a MASSIVE dose of superthrive (1tsp>, But all its doing is harming your plant and distorting your schedule. And only use it on a plant once at most twice .
