As for the blooming/fruiting issue, your fertilizer may be too high in nitrogen. If so, you will get plants with plenty of foliage growth but little to no blooms, which means no fruit (peppers). You can offset this by adding some phosphorus rich fertilizer or bone meal to the soil around your pepper plants.
