I'm not really sure what to call this water, and I don't know how many of you have access to it, but it smells a bit like sulphur when people use it to water their lawns, so we call it sulphur water. I think the government calls it reclaimed or ground water, it's only semi-treated and not safe for drinking.
We decided to try using this sulphur water to water our plants. They say it's safe and even beneficial for plants because all of the nutrients (fertilizer run-off) haven't been removed. They also say that using it instead of the normal water will reduce your water bill because there's no charge for the semi-treated water.
I watered with this stuff, every other day, for a little over a month.
The worst of the damage is gone now. It started with the edges of the leaves, first they'd curl up, then they'd go yellow, to brown, dry out and fall off in bits. This progressed through the leaf, leaving bumps, dead spots, and holes until the entire leaf was yellow and falling off. There was also a noticible difference in leaf size, and flower size, smaller than normal. Also, the plants in pots were drying out quicker.
When we first started noticing problems, we went through every possibility. The only thing we could think of was the water, so we switched back to the normal water.
This is new growth on the same Brug, after just a few weeks of using the normal water, they all seem to be coming back from the trauma.
One more picture,
In this one, you can see the older, damaged leaves behind the new, healthy growth.
Just for the sake of it, I pulled out our aquarium test kit and checked the ammonia and pH levels. The pH seemed ok, but the ammonia was sky high, right off my chart that ends at 8.0 ppm. For those of you not familiar, a fish in this water would be floating belly up at the surface.
I found a very hidden website last week that stated that while this water is ok for grass and some species of plants, it can do severe damage to other species, and even kill some. I think Brugs and Daturas are some of those species that don't respond well to this water. Also, Nicandra, almost every seedling we had died while we were using it.
Sorry, I know this is a bit lengthy, but I wanted to tell you all to be careful with this stuff, even if it's just Florida specific, I know there are several other members here in Florida, and they may have the option of using a similar water.
