Chlorine (Cl) - Needed for photosynthesis; stimulates root growth and aids water movement in plants.

Chlorine is necessary for osmosis and ionic balance; it also plays a role in photosynthesis.

Chlorine (Cl) – this element controls water uptake and transpiration. Stimulates photosynthesis and is a major constituent of the anthocyanin molecule. Deficiency – plants wilt easily. Bronze colored leaves with dead or chlorotic spots, stunted roots with club-shaped tips. Toxicity – saline poisoning, small dark leaves, burned margins and wilting.

Has anyone heard of this before? I'm sure this is just trace amounts that they're talking about, but I thought it was interesting.

It's true, and sodium (Na) is important for some of the same reasons but don't take that to mean that your plants should be getting sodium hypochlorite (bleach); although in hydroponics table salt (NaCl) may be supplied in very minute amounts to meet the sodium and chlorine requirements. Humans need these elements as well.

Chlorinated tap water will have free chlorine, probably chloramines as well and chlorocarbons (which are much more toxic). Most municipalities aren't using enough free chlorine or chloramines such that it would kill any plants, they really shouldn't be anyways. The real concern is for for the microbes, at least some of which will be killed by such disinfectants. Microbes are extremely important to organics gardens, so un-filtered chlorinated tap water should be avoided in organics. In hydro RO water is used so that grower knows there aren't sufficient levels of dissolved minerals to cause problems.

In a huge number of places, Chlorine has been replaced by Chloramine and the latter can not be bubbled out....

I've been letting the water for my compost tea sit over night and aerate with a air pump, but lately I've been using straight from the tap with my straight watering.

I'm not sure if this is true, but this guy says it can evaporate.

"
Degassing

<li id="jsArticleStep1"> Some vegetable growers worry that the chloramines in the water will enter into the plant's roots and harm the plant. The chloramine combines with the sodium in the tank to form sodium chloride or will degas and leave the water as a gas. Those gardeners worried about the effects that the chlorinated water will have on their plants can eave the water out long enough for the chlorinated water to degas itself."​

He starts off with chloramines and ends with chlorinated, so maybe he is mixes up.
