I'm not familiar with that brand, but check the nitrogen levels. Many bloom formulas have enough. Also, does your soil have a starter charge of fertilizer? If it does, you'll be good to go with that autoflower. Otherwise, try to find some guano at a garden store. This advice only pertains to soil or soilless, not hydro. If you're running hydro, I think you'll need to find some sort of grow formula, even if it's not the same brand.
Good luck to you.
