Just get as many plants as you need for as many types of water you need to use, than look up the ingerdients in each type of water, and you can say what affected the plants most. I'm sure that each type of water has a common ingredient, but the ones that affect the plants the most, look at their ingredients and see what they have in common. Than, the one that got affected the MOST out of all of them see if it has more of one type of ingredient than the others.
