Is this all tomato blight or something else?
Last week I realized I think all of my tomato plants have blight .... or some thing.
Below are pics.
In general I think the plants are are quite healthy growing and producing rapidly.
The second two pictures are of what I thought was blight.
It is the last picture I am unsure of. Is this blight or something else. The spots are tiny and more numerous. One plant has many leaves with these spots but the plant is otherwise strong and healthy looking.
So far what i have done for the plants is mulched with grass clippings, picked off infected looking leaves and sprayed with a baking soda solution.
Re blight should i be picking every single leaf at first sign of yellow or spot or wait for it to become more appearant that it is blight?
How often can i spray the baking soda solution?
