Welcome to the forum!
African violets only bloom when their roots fill the pot (not the same thing as being root bound, though), so it could be awhile before you see any flowers.
Some regular potting soils are too heavy for the delicate roots of an African violet. I prefer to use a soilless mix made especially for these plants. I've never used Scott's, so I can't say whether it will be okay or not. Unless it's
very heavy, though, I doubt it will be a major problem for your plant.
Pruning away the unhealthy leaves was good. Continue to do so as needed.
I only use plastic or glazed ceramic containers for my African violets. Unglazed clay can absorb salts from the water and fertilizer, and if the leaves or petioles touch the rim of the container, those salts can cause damage to them.
I water all of my plants from the bottom. I place them in a tub, or the sink, and fill it with water just deep enough so the containers don't float. As water is absorbed, I add more water to the tub, until the depth finally is just above the level of the soil in the pot. You don't want the plants to float, because they can tip over. That's not really good for African violets. When water is visible on the surface of the soil, I remove the pots and allow all the excess water to drain off.
Fertilize only when the plants are in an active growth period. You will see buds deep in the center of the plant at those times. The plants rest for awhile, and fertilizing them when they're at rest will only increase salt build up in the soil.
African violets need bright light, but not direct sun. A few hours of early morning sun is usually okay, as is an hour or two of very late evening sun. They will also do well if placed in a sunny window, but a couple of feet back from the window glass, so the sun doesn't actually hit them. Sun filtered through a sheer curtain would also be okay for African violets.
Does any of that help you?
