Live moss as test for TDS?

So live LFS gets dark at the tips when it's in media or water with too much mineral contamination, right?
Is it, therefore, a safe assumption that any media or water that doesn't turn moss dark after a month or so is free of TDS, or does that only mean that it's free of certain darker minerals?
