Greenhouse vegetable leaves have a massive dead spot

Ammonia poisoning. The light leaves of the vegetables showed indeterminate massive patches and the leaves were burned. The roots of heavy plants are dark brown and lose their functions of absorbing water and fertilizer. The above-ground parts gradually wither and die. Ammonia can be discharged. When the pH is above 8.2, it is more appropriate to vent the exhaust. In addition to releasing air, it is also possible to reduce the concentration of soil-fertilizer solution by rapid irrigation. The active liquid fertilizer is sprayed outside the roots to balance the pH of the plants and the soil. Spraying 1% edible vinegar on the back of the leaves of plants can reduce or mitigate the hazards.
