Tomatoes are a big fail!
Hello, this is my first year growing tomatoes.
At first, they started showing signs of blossom end rot (not sure though if it's blossom end rot) on the fruit, and I applied some cold coffee to acidify the soil, about 3 cups already, and a week later still no signs of normal tomatoes, and I know for sure that it's not a problem with calcium in the soil.
Then some of the stems began to get dark brown, and the tomatoes on them took a yellow tint and began to get wrinkles on them.
Is it a disease?
