Pepper turns red at seedling stage, which may be due to the influence of light, drought, insufficient nutrients or the application of some drugs (such as plant growth regulators).

In the case of sunshine, drought or insufficient nutrients, the leaves of pepper will turn red in advance. In addition, if plant growth regulators, such as analogues of fresh vegetables, are used, pepper leaves may turn red prematurely.

Of course, the above situation does not include the red caused by pepper blight. If your pepper plants have the above problems, it is recommended to consult a professional for diagnosis and treatment.
