White mold, with some tiny black balls. It started durring the Summer, now it has spread to almost every plant. I tried to control it with garlic water but it seems it was not effective and I had to stop using it because of the smell (which I do not mind but others in the house do).
The burned parts appeared during the Summer's high temperatures and the plants are exposed to direct sunlight so they were attributed to sunlight. However, it is november and they still ravage the plants.
Basically, I have no idea what is wrong. PH is good, soil is moist, fertilizer was applied frequently (stoped two months ago) and I live many hundred kilometres from grape fields.
The white mold shows a fungal pattern under a microscope. Unfortunatly the microscope does not take pictures.

Uperside of leaves from three different plants.
