Gravity is super twitchy stuff.
If you use it in hot or super intense light conditions (=light closer than recommended), you can easily burn the bejeebus outta your plants. I've done it, lol.
If you use it, follow the directions to the LETTER. If you can't follow the directions for whatever reasons, I'd skip it until you have a better setup that allows for raising the light, and go with a gentler carb-supplement type bud mass enhancer.
