My plants don't seem to be doing so good, and I think it's because of the water I've been giving them. When I was at my university last year, I gave my Nepenthes Ventricosa tap water and it thrived. Therefore, I've been giving my outdoor plants tap water, and my plants appear to be getting smaller and weaker. For example, my Drosera Capensis is producing really small leaves and the leaves won't curl around insects. My Sarracenia have really slow growth, and my new Pinguicula Caerulea is really small.
It appears I have to give them purified water. However, there's a drought where I live (Florida) and I don't want to buy gallons of distilled water because it's too expensive.
