I was wondering if I should adjust the pH at a scale? I have root'n grow and thought maybe should be adjusted to the 61.4 range as that's where it's best uptake is my best guess.
Hydro. Roots just are blah. Not liking the growth rate at all. What I understand is that between 6 and 6.2 is where the uptake for it and I meant from 5.5-6.2
