Kidney bean bend:

1: Variety problem.

2. The fruit is bent due to low temperature (the tail is a little sharp).

3. Lack of boron will bend, and beans and rice will be less.

Suggestions: firstly, the temperature should be controlled above 15℃; secondly, the fertilizer and water should be balanced; thirdly, the leaves should be sprayed with brassin+potassium dihydrogen phosphate+boron and molybdenum.
