seedlings with yellow leaves , overwatering?

[The_word]

Yes I used to live in a city near Barcelona (Rubi) and tap water was drinkable but since I moved north to the rural areas the water is awful. I think that just by tasting it you can tell when tap water is drinkable, unless youre used to drink heavy treated tap water only. I should ask for a report but I know its not gonna be good...

Just buy a water purity testing kit. They only cost a couple of euros and you can see where you need to make adjustments.

I will have a ppm meter by the end of the month for more accurate readings on water hardness.
