Rain water contains nitrogen and a number of elements that are bad for your plants. Also superthrive is highly concentrated. You really do only need 1 drop per gallon.

I would flush your pots, and water it with distilled water.

What type of soil are you using? Can you tell me the brand or post what it says on the front of the bag?

I suspect it's a combination of things that is creating the problem you see.

Also are you able to get any pictures?
