To the pH 7.9 plant in question… I tossed LITFA out the window, leached the container with 3x container volume, first with 1/2 vinegar, then 1/4, then plain 6.0pH 80ppm. Runoff clear. pH 5.9 1 hour later, pH 18 hours later is… 6.1
i’ll wait until that pot gets light, water with 6.3 pH, & do the wait & check again but i already see “de-purpling” in the stems 
.
