Eggplant

Hello... I need some serious help with my eggplant plant. I planted two eggplants in separate containers abt a month ago. Both are beginning to flower but the leaves of one of them is turning brown. What do I do? I fertilize accordingly and water both plants at the same....both are in the same type of container with the same exact potting soil mixture.... Do u think its a disease? I didnt see any bugs/worms on them... Please any help will be appreciated. I don't want my plant to die. :(
