With good soil and a 3 to 5 gallon pot, you can grow outdoors (and indoors) with no added nutrients. My advice to you is to only use nutrients when you see that the plant is showing a deficiency, if there is no sign of the plant needing anything extra, there's no need to actually feed it, Let the plant feed itself from the soil and by the looks of it, those pots are gigantic. If needed I would only use a grow nutrient, bloom nutrient and cal/mag if your water is too soft.
