Usually a buildup of salts due to a lack of soil drainage. You need to have holes in the bottom of your containers and some gravel in the first 2" or so. Your plants can't absorb nutrients with high PH levels. I would repot your plants with new soil as above.

Potassium K+, calcium Ca2+, Magnesium Mg2+ and Sodium Na+ ions are the main contributors to high soil pH (i.e. they cause the soil to become alkaline).

Why do you put manure on limestone soils?
Low pH of the manure counters the high pH of the soil. Acid manure, alkali soil.
How does the chemical properties of the soil relate to soil fertility?
One example is pH. It is more difficult to make soils which are very high or very low in pH as productive as soils with a more neutral pH. The nutrient minerals are made less available to the growing plants, forcing the farmer to apply nutrients at higher levels than they would otherwise. Example: soil with a pH in the 8.0 range is high in calcium, which bonds with phosphorus, making the phosphorus less available to plants, so farmers have to apply more phosphorus (or coat the phosphorus with a polymer to protect it).

What causes potting soil to smell like ammonia?

What is a sentence using humus?
"Humus is in soil," "the humus levels were high," Did I answer your Question?
Can you neutralize high phosphorus levels in the ground?

How do you test the soil with a soil testing kit?
There are soil test kits that are electronic and measure the soil levels. There are also soil test kits that use the small amounts of your garden soil and mix with the testers ingredients to read the levels.
Why is it important to control soil acidity?
Many plants (especially grass like plants) do not grow well in acidic soil. Also, unnaturally high levels of acidity in a large amount of soil can leach into the water table and taint it.
Why should you test your soil for Ph and nutrient levels?
Certain plants grow well with certain levels of nutrients. Too high of a pH can actually be bad for most plants because this means there is too much acid in your soil. For one, it can cause your soil to erode, but it can also prevent your plants from reaching their full potential.
Is acid rain a problem for all plant species?
no not always because it causes acid levels in the soil to rise and cause most plants who are not adapted to the soil acidity to die but there are a few plants that can survive in those conditions
What natural soils are considered to be the most furtive?
The natural soils which are considered to be the most furtive is the soil on Hawaii and other volcanic islands, because the volcano has enriched the soil to have high nutrient levels.
Describe the three main causes of pollution of the earth's waters?
