The white spots on the leaves of your zucchini are very common and appear to be a natural occurrence. The leaves are capable of adequate photosynthesis to sustain the plant and to produce fruit. The variation in productivity of the plant is also a common event.

Continue to monitor your plants for any other problems and provide them with routine nurturing.
