I think you would have to go as far south as possible to find that soft water (coastal areas), only ever seen hard water in LondonPH'ing is for hydro & southern soft water shandy drinkers, err growers i mean.. up north it's hard and fine out the tap with most nutes, canna works a treat with it.
Canna works well without any need to measure or adjust PH,
water starts at around 7.2-7.4 when brought up to an EC of 1.0 the PH will drop to 6.8-6.6
EC of 2.0 the PH will drop to around 6.2 anywhere around 5.8 -7 works well in NFT and DWC
i used canna for about 10 years , but switched to vitalink max about 5 years ago i find it keeps them greener and is a bit cheaper to buy
all these foods have virtually all elements supplied in chealted form and hard water and soft water versions, adjusting PH should be unnecessary
