I've heard a lot of different methods for watering plants, especially regarding types of water to use. Each plant is unique, but I've come across suggestions to use leftover spaghetti or potato water. Before I give those a shot, I'd love some advice from you all. What are your best practices for watering plants?

Honestly, for most plants, regular tap water works just fine. I wouldn’t recommend going for things like starch water; I don't think they add much nutritionally. If you have aquarium water, that’s a fantastic fertilizer, but it’s not a must. If you’re worried about your tap water being too chlorinated, just let it sit out overnight and it will be fine. Most plants can thrive on regular tap water.
It really depends on your location. I've been using tap water for over 20 years with no issues at all here in Finland. I can't see the need to go for potato or spaghetti water when tap should do the trick.
I actually use my aquarium or indoor pond water to water my plants. It's great because it has a much lower electrical conductivity than regular well or softener water, which can be better for some plants.
