Ok thanks guys.
pH meter checked, calibrated, double checked, that's ok. Stable overnight at 6, I think I can eliminate that.
Need to get ppm calibration solution. I have 2 meters, they are about 130 out, but that shouldn't matter a huge deal.
I need to stop giving you guys ppm including the 200 of my tap water. So in reality she got about 450, which has dropped to 400 in 36 hours. 450 seems very low. If the lower of the 2 pens I have is right then it's more like 300. The damage looks like a deficiency to me.
So i'm very tempted to whack the ppm up to at least 600 and see how she responds...what do you think?
Cheers!
