No, I havent. But I can't imagine that PH would still be an issue if I add lime every watering. I'll see about a meter.[/QUOTE
who told you to add lime at every watering?...lime works instantly and CONTINUES over time to raise your soils Ph....a very alkaline medium is just as bad as acidic.....also Cal/mag toxicity will lock out some major mobile elements....which is what were seeing.....never add anything unless you know your ph,a meter is also necessary in soil; it's just used less a poly stated.
don't like the meter your buying either....the probes to short, need to hit the root zone or are you planning on digging up samples
