You need some Epsom salts in it. On the package are instructions. Or google epsom salts. Have used this for years.

Also, clean up your bottom of the plants. They need air space. Good rule of thumb is nothing closer than 10 inches from the ground. Remove all plant materials. Both these suggestions also take care of bottom rot from tomatoes too.

OH, never splash water on your plants. They prefer being watered by laying the hose on the bottom dirt. Gentle flow rather than hurried spray. Rain water is different. That comes anyway and washes the plants. Hose water is not the same as rain water.

It is my belief that what you are describing is Tomato Blight.
It is a disease which can turn all the leaves yellow, then brown. Interestingly enough, it doesn't seem to affect the fruits. It's almost impossible, at least for me it was, to do anything like apply this or that and fix the issue.


Like someone else said, if its a pole variety, pull off all the lowest branches until you come to one with fruit. I like to keep my stalks bare up to a foot from the ground. That usually takes most of the brown leaves off. Water Tomatoes regularly, they don't like overwatering or underwatering. But a good deep watering once a week, followed by regularly checking the dryness of the soil, there is no one set formula.

Sometimes its windy, the plant uses more water, sometimes its hot and more water evaporates than gets to the plant. The variables are there so check your tomatoes daily and if they need water, give them some. regular correct watering fixes almost every problem in Tomatoes. Next year be sure to plant them in a different location, and also consider buying a blight resistant seed, because,


I find, that once you have blight, you always have blight. I switched to blight resistant seed and have noo issues for the past 2 years.
