if you want the best from using p.h, use an e.c meter to check the water's and neuts electricity's conductivity. and just like p.h one can adjust the e.c levels up or down. but imo, food, smoke ect that has been grown with chems and hydro are fat and empty of taste. its bio all the way for me. i have been working on my own version of bio-ponics. big pots of watered soil, the bottom of the pots kissing the top of a tub full of bubbling neuts. so through the plants veg stage they have been grown in soil and by the time the roots hit the dwc tub at the bottom the plant should have started flowering and one can fine tune the amount whatever they need. also sugar mollasses is the key to taste and good bacteria to the roots.
