I might be wrong but: pH doesn't work in a linear manner, it is a logarithmic measure of H+ ion concentration. So you can't say mix 50/50 pH 5.0 and 6.0 and be left with pH 5.5.
Your water's pH seems high, I mean maybe your soil needed some additional buffering capacity to start with, but by now you would think it would be ok to water with pH 6.5?
I don't use soil personally, so might be shit advice. But I have been told that many nutrients are locked out around 7 and above, so this could be a source of your woes.

Good luck with the girls.

Yer thats 'hydro ph talk' sir!

What happens in soil is the roots are in soil not water and the pH of the soil and salts affects the roots pH-wise. Soil contains lime usually which buffers acidic water, fertilizer and yes hydrogen H+ions.

I water at pH8.1+ with no ill effects, pH in soil is not like hydro but if you have any more questions on soil pH id be happy to try and answer them for you, took me a while to get the hang of it too. Peace

Haha well i've just started some acid/base equilibria at uni, so i'll ask my lecturer today.
I should probably check the runoff from my coco next watering too...

Acids and alkalines are not related, acids is the measurements of hydrogen ions in a solution and alkalines are the measurements of the ability toi neutralise hydrogen ions or acids.

Like hell is he gona know anything about soil based pH!lol! Peace

Sounds very achievable. They seem ok and healthy in places but some parts seem small nute or environmental issues, as long as they stay like this i think its all cool. Well done.
