Sorry to jump from post to post, I never saw this one. The NPK numbers you see on the Sugar Peak bottle stand for nitrogen, phosphorus, and potassium. These are three major chemicals that generally define the attributes of most major commercial fertilizers. Having a higher percentage of nitrogen during veg is preferable to encourage foliage production, and a greater phosphorus/potash percentage is used to promote fruits/flowers in plants, and vigorous root growth.

Many fertilizers also contain micro nutrients (trace elements) which are meant to conservatively apply other nutrients that the plant may be deficient of. If you've done a lot of flushing recently to try and correct pH issues, then feeding with a 1/4 strength fertilizer (preferably with micro nutes) would help to get some of these elements back in reach of the roots.

Superthrive isn't actually a nutrient, or at least, I'm pretty sure it isn't. I think it's more of a supplemental source of vitamins and growth hormones. I only use the stuff for clones and transplants to promote root growth, but other growers absolutely stand by the stuff for all sorts of growth stages. Fertilizers with micro nutrients and Superthrive are available online, at hydro stores, and maybe even some hardware stores like Lowe's. Just be careful if you decide to pick up any fertilizers from Lowe's, as most of them aren't very suitable for cannabis.

Take a few hours, roll up a couple of spliffs, and spend some quality time going through a lot of the posts in the growing forums here. You'll get some good ideas and feedback about specific fertilizers, regimens, and so forth.
