Why do my cucumber leaves have white spots
Types of spots on plant leaves
If the leaves of the plants have white spots, it is because the irrigation water has an excess of lime. The solution is to spray with a mixture of water and vinegar (one tablespoon per liter will be enough).

If you want more information I recommend this book: Pests and Diseases in Vegetables and Fruit Trees, you will find very visual information on how to detect, prevent and treat specific pests and diseases of crops.
Horsetail (Equisetum arvense) is used as a fungicide for fungus control, due to its high silica content and the presence of a toxic saponin for fungi called Equisetonin, which are effective for the control of various types of fungi that infect the plant:

What is the name of the plant with green leaves and white spots?
Powdery mildew on cucumber is a disease caused by two pathogens: Erysiphe cichoracearum and Podosphaera xanthii. We are talking about a parasitic fungus that settles in the plant and benefits from its own plant mechanism: it penetrates the cells, consumes nutrients and causes the development of a disease that affects the yield of the plant.
Powdery mildew is a fairly common disease of cucurbits. As in the case of other fungi, powdery mildew needs moisture to grow and develop, so the risk of its appearance is higher in areas with high humidity, after episodes of persistent rainfall and in environments with temperatures between 10 and 20ºC.
Identifying powdery mildew on cucumber is relatively simple because the disease will cover the leaves, fruits and branches of the plant with a kind of white veil that reminds us of ash.
The disease is most visible on both sides of the leaf, where the characteristic white powder usually gives way, when removed, to yellowish spots. The presence of this cucumber disease reduces the photosynthetic capacity of the plant and hinders its respiration. In practice, the leaves end up drying out and the plant’s production capacity is affected, which prevents the rest of the fruit from developing optimally.
White spots on plant stems
Currently, Mexico leads the world cucumber export with 25% of the total volume exported and is the world’s leading exporter of this vegetable to the United States of America, supplying 90% of its commercialization.
It is a herbaceous, annual, creeping plant covered with bristly hairs, with fasciculated roots and quite superficial development, with the highest concentration of roots between 25 and 30 cm. The plant is characterized by climbing or creeping stems, highly branched at the base, with four marked angles and simple tendrils (not branched).
Downy mildew is one of the most important foliar diseases of cucurbits. The disease occurs in temperate and tropical areas, with heavy or light rainfall, provided that sufficient periods of leaf wetness are provided, usually by spraying.
The leaves show well-defined angular spots, yellow at first, then turning light brown to gray as they age. These lesions may coalesce and involve a large portion of the leaf.
