They should be flowering after 4-6 weeks. Generally this is a sign of too much nitrogen and not enough potassium, you will need to mix it into the soil or get a water soluble type to water around the root zone. You can add Sulphate of Potash to increase the potassium which should encourage flowering and fruiting. you could also try calcium (dolomite lime) this will also make your soil more alkaline so would help to do a soil test first. If your soil is a clay type you could use gypsum instead to help break up the soil, it is also high in calcium.
