Just a comment.  If you use rainwater, it contains nitrogen. I'm not sure 
who told me this but, I was told that lightning causes a reaction of 
somesort, that ends up producing nitrogen. I find that plants watered 
with rainwater tend to grow much better for me than when watered with 
other sources of water.  Maybe its all psychosamatic!
