I started growing tomatoes about 2 months now. Planted over 500 plants and they all started off a healthy green until recently. Some odd plants here and there will turn a deep dark green colour and become crispy in texture before gradually turning brown and eventually dry up. They also don't have a strong tomato scent like my other ordinary plants. Tried searching everywhere on the internet for the same symptoms and a solution but haven't had any luck. All of the plants aren't like this (see the last 2 pics of healthy plant at the end) but every other day I'll discover some plants turning the exact same way. I also want to add that the plants that are fruiting don't turn like that. I'll add details below about my setup to get better help:
-
I'm living in a hot and humid tropical climate (all year round).
-
The tomatoes are covered with 50% aluminium shade netting above.
-
They get watered once a day in the late afternoon just before evening.
-
I haven't used any herbicides or pesticides.
-
They're grown in 5 litre plastic grow bags.
-
The variety grown is the money maker tomato plant.
Is it a nutrient deficiency or perhaps a fungus/virus? I can't seem to find similar results on the web to help my case.

Could be pesticide damage
This doesn’t look like a virus or nutrient issue. It’s more likely **root stress** from heat and moisture in small containers. In a hot, humid climate, 5-liter bags plus daily late-afternoon watering can leave roots too warm and low on oxygen, which causes dark green, stiff leaves that later brown and dry out. Try watering in the morning, let the soil dry slightly between waterings, make sure drainage is good, and move plants to larger containers if you can.
