Tom, I am so very grateful for that you have been willing to share your extensive knowledge here. I am new to the forum and am grateful I stumbled upon something you wrote which led me to search out your wisdom even more.
I too am dealing with a serious root infection, although I realize this threat is old.
In this thread you stated as the next solution to "mix your normal" and I am wondering if you are referring to mixing with distilled water with salt or the citric acid version. I am so much more comfortable with the way that you have advised mixing (not with citric) but this statement makes me wonder if for this specific root treatment you are advising the citric acid .
