I'm growing a few plants at the moment but I'm unsure whether to use london tap water on my soil because I've read on the website that thames water is hard-very hard and in my area it's supposed to average 7.8. Perhaps I'm worrying about nothing but the first plant I grew from bagseed and fed just tap water may have show some deficiencies. Has anyone here grown successfully with london tap water? Thanks.
