It seems that some controls need to be setup before concluding that Chlorine is the culprit. I'm not saying that you're wrong, Edward, but it would give you a much stronger argument to make controls. Although impossible, since tap has lots of things in it, would be to remove the chlorine only from the tap while leaving everything else and seeing if there's a change in the growth habbit. For another control I would take your carbon filtered water, which has shown good growth, and replenish it with chlorine, and then look at the effects. And finally, to isolate chlorine, I would take R/O water, replenish it with chlorine at varying doses from 1-50 ppm and see if there's a differential effect based on the concentration of chlorine to the growth habit of your plants. Lots of work.... but just thoughts...
