Yes, that very one. And, just the veg, fruit and flower food for now. It contains microbes (Rhizobacillus) in the granules of ground organic matter (meat meal, bone meal, blood meal, feather meal, wheat middlings, alfalfa, etc). NPK is 3-4-2 which may sound low, but it's because it's organic and it's meant to allow you to build around it for the two different stages nute-wise. I water with molasses to increase the microherd and plus it increases potassium. Eventually, you should also get Dolomite Lime and FoxFarm Bat Guano (HIGHLY recommend; contains myco and humic acid, 0-5-0).
But for now:
-Potting mix
-Veg/Fruit/Flower food (3-4-2).
Then you should be good until payday. $5 for an 8-quart, 11 for the big bag. And the food is about 7.
