EDIT:
Tap water is almost always FINE. Please don't try to answer problems when you've got no experience of them.
My apologies but I've read so much in so many different places about hard water problems that I thought I was helping, and I did point out that I'm not an expert and not to act on my advice aloone.
I'll just stick to what I actually know from now on.
brainfood33 Reviewed by brainfood33 on . Grayish/brown/purple?! Leaves, I have no idea what color they are! I could really use some help here guys. I have three plants and two of them are doing good but this is the smallest one and both bottom leaves are turning like gray/purple and it looks like tiny white dots in the picture but they're tiny and they don't move, so I don't know what that is. This plant originally was doing the best of all three but now hasn't grown much for a little while. I really haven't got much help from anyone else so I'd appreciate if someone threw me a frickin' bone here. Rating: 5
