I ran into an issue early on with water. We have a water softener and most plants don't like a diet of that stuff.

I wanted to get everything started early and didn't want to use the softened water and it was too early (still freezing) to use my irrigation water supply. So I set up a system to catch water from the metal roof of my shop.

It turns out the plants didn't like the roof water, some died and others had their growth stunted.

I then started to carry buckets up from the river to water all the starts. They liked the river water.

Water problems can take weeks to show up, then additional weeks for the plant to respond to good water, if it even will. This set me back months.
