CHLORAMINES CAN KILL YOUR PLANTS

I posted a article a few weeks back titled "chlorine overdose" http://boards.cannabis.com/search.php?searchid=17886
thanks to some insight by some one who posted a comment about
chloramines. this comment showed me that i was out dated.
I never herd of this, but I had to find out more.
I have been doing a experiment that I do each year.
it is to find out how long the concentration of chlorine takes to break down.
here how the experiment works.
I take 9 plants, 3 sativa-indicia hybrids, 3 indicia and three sativa plants.
the hybrids are clones that I been growing for the last few years.
the other 6 plant are from seeds.
I put 1 from each in to a control group.
the first group get only bottled water, the second get tap water less then 24 hours from the tap, the third group get tap water that has been in the sun for 2 months or longer.
this to make sure that there was sufficient time for the chlorine to break down.
group 1 are really green, averaging 1+ inches per day.
the second group did not far so well, it started with chlorotic tissue starting from the bottom of the plant, older leaves first, then necrotic tissue set in on all the affected leaves.
the only leaves remaining after 3-4 weeks were the growing tips, which grew very slow if at all. chlorotic tissue started as little spot that looked like the plants were salted, with red appearing in the stems an petioles.(the red in the stems appeared almost over night)
and the third group followed the second group, but at a slower pace.
now if it was chlorine, it would, or should have broken down after 2 months,
but I still had the problem.
that's were the insight of (thank you scribble2010)

came in very handy,
I found out that chloramines is a very stable chemical, made from joining chlorine and ammonia molecule together, in doing this the chloramines does not break down so easy, hence, stability.

back to the experiment,
to correct the problem you would think to flush the soil, but you would be wrong, or at lest partially wrong, the microorganisms in the soil work under 2 conditions,
wet and dry. the wet is probably dieing or dead.
if you were to ad water now you could accelerate the problem.(in the extreme cases)
what I did first is to let the soil dry out as much as the plants could tolerate.
then add only necessary amount of water to keep it alive, about a week or so health increased, and slowly increase the watering amount with small amounts of NBK.
I did this to control group 2, but for control group 3, I put it out side in the rain, and you could see improvement in just a couple of days.
now if you know any thing about science, you know that a experiment has to be confirmed.
I took group 1 and gave them TAP water, that right, I fed them the poison.
and in less then 24 hours you could see the problem in these plants.
I left them in the rain with the others, and they recovered fully.

So the moral to the story is that the tap water is not fit for man nor beast (or plant in this case) it is only good for the Lu or laundry.
