I planted some vegetable plants such as eggplant, tomatoes and different varieties of peppers, but all of them are mostly growing leaves. Some plants got flowers and they dropped off and some got 1 fruits like 1 tomato and 1 pepper, but it's size was very tiny. I live in an apartment so all the plants are in containers. Tomatoes are in 5 gallon containers and all have good drainage. They are planted in potting soil (Miracle Gro) except tomatoes which has a mixture of peat moss and potting soil. I water them twice a week or when the soil dries. Was thinking to feed them with some solution/good fertilizer but hardly have any idea of which solutions or fertilizers are good for these plants.
Any tips or suggestions. I reside in Kansas, USA so temperature wise it's summer in here now and very hot usually 90's F.
