Do tomatoes turn yellow first?
From green to yellow or red Tomatoes are green when they start growing and only when they stary ripening is when they start turning red. The green colour in tomatoes is caused by chlorophyll.

Why are the bottom leaves on my tomato plant turning yellow?
Also, as a tomato plant ages, it gets more leaves at the top. These top leaves shade the lower leaves from sunlight. As a result, the lower leaves are not able to produce as much energy from photosynthesis. The plant will then draw nutrients out of the bottom leaves and use them for growth of higher leaves.
What do the first leaves on a tomato plant do?
The first leaves (the ones nearest to the soil) on tomato seedlings, called cotyledons, are not real leaves. Their primary function is to provide nutrition to the seedlings while true sets of leaves develop and start the photosynthesis process. True leaves are the second set of leaves all garden plants grow.
How to keep tomato plants from getting blight?
Wet, humid conditions exacerbate early blight. Mulch heavily in the entire tomato area, creating a barrier between the soil and the tomato leaves. As the young plants grow, cut off lower leaves completely, especially if they are touching the ground (even if they’re healthy). Leave a 12-18″ gap between the ground and the lowest sets of leaves.
Why are the leaves on my Fusarium plant turning yellow?

Why do the leaves of a tomato plant turn yellow?

What to do if tomato plants have brown spots on their leaves?
Remove the affected leaves as soon as you notice any spots forming. If that does not seem to help and the leaves continue to turn brown, use a fungicide and spray it directly onto the affected foliage. Use an environmentally safe fungicide to protect the health of the unharvested fruit of your tomato plant.
