i have just read an article by amano which suggests that hard water prevents a plants uptaking max nutrients. seeing as i have the hardest water area in the uk (very hard) this may be affecting my plant growth. i have never been able to grow stems to look 'lush' they allways look as if they are missing something, even when double dosing EI. and seeing as stems are fast growers this may be the cause. i was thinking with all the snow about it may be a good idea to stock up on soft clean water do you guys have any views on this?
