Best Starting Mix For Vege Sprouts

Question

Planting the “Sprouts” in potting soil: I have good “store-bought” potting soil … I move the mature sprouts from their sprouting site to small 2-3 oz. …(6 pack plastic trays) …. (Inside 78* house) It would seem that the new plants don’t require much in the way of supplements in the beginning… Just simple dead planting medium… Correct? But then after they get real leaves … I move them to 8 oz. Styrofoam cups w/ holes. That’s mostly when I am wondering … should I supplement the potting mix with: 1) potash 2) epson salt 3) Mycorrhizal Inoculant 4) seaweed powder 5) Blood meal ??? I mean … don’t they need some Food etc? How do they grow those healthy plants (in the stores) that are a foot tall in a tiny tray? I know it’s probably in an ideal environment … but what do you think is the medium?
