Alkalinity: Focus on the Water Alkalinity, Not the Water pH 

It is chemically similar to auxin growth regulators so some plants could be sensitive.

The Cl component will form a chloride with every plant mineral imaginable. It is said that certain forms of chlorides will "lock-out" for such an extended period that some garden writers have said; "your grand children will be lucky to see it in plant available form again". Avoid excess Chlorine. Never seen a farmer fertilizing with bleach, it's a bad idea. Just use salt NaCl. Sodium at acceptable levels (2% max) will keep Cl in check. HCl, though often used, is considered risky considering the "salt" component of most fertilizers provides ample Cl and the dangers of excess Cl.

Chloride toxicity. Cl is an essential micro nutrient but it is common in ground water and many fertilizers (Often obscured with the name "muriate of potash", which is potassium chloride.) the amount needed to neutralize alkalinity is too much. Most of what Sam wrote is wrong, and you can check chemistry sources such as solubility tables.
