Four Way Mirror

Still struggling to get the medium pH up been adding Potassium bicarbonate last 2 waterings (in going pH 8.9) still getting out of range low 5 runoff numbers, left off Cal/Mag last time to make sure there is no acid in the mix. Just anxious to get this grow done, think I went to heavy on the AgroThrive early on thinking it was weaker than salts, it certainty is not, lesson learned the only other thing I thought might help is a help is adding microbes to widen the pH range but it might be too late for that at this point. 😕
