Nutrient excess
The most common issues for plants are nutrient-related. And they can be caused by lack and excess nutrients. For proper functioning, plants need a more significant amount of macronutrients than micro ones. But, of course, imbalance often happens. Potting mixes that are entirely soilless contribute to the problem as well as unbalanced nutritional programs or water alkalinity. The worst part of this type of problem is that it’s hard to recognize it immediately due to the subtleness of the symptoms. And every case is unique because different cultivars react differently on the deficiency of nutrients or their toxicity.
