For the farmer or gardener, it is important to be able to read your plant. The seasoned grower develops an intuitive sense over time in response to plant signals of stress. The key is observing and being able to notice unhealthy leaves, and developing the ability to understand what the plant’s leaf is telling you. Something to note is that a young leaf’s message differs from an old leaf’s message.
While there is some overlap between the illustrations, they should be helpful as a whole in helping you figure out your specific problem.
