So sorry but your warm climate can be a challenge for growing veggies and so I will need to refer you to your local extension agent. A local nursery person or Master Gardener will also be better at offering you suggestions than me as my experience is limited to gardening near Seattle, Washington. My guess is that your tomatoes suffer from the high humidity in your area. Local growers will be able to tell you what tomato varieties do best in your climate. Keep growing, Marianne Binetti
