Re: [APD] Adding Carbonates

["Philippe Lemaire" <ph_lemaire at compaqnet.be>]

I have 50 mg/l (Lamotte test)...
Back from a time I was at 2000 mg/l !
Still difficult to put down to the 25 mg/l Tom Barr suggested
As N ist at 30 mg/l and P at 1.5 mg/l
As Ca is at 60 mg/l and Mg at 12 mg/l
KH 4, pH 6.5
Fe ?

I'm still asking why some plants are not going well...
H. zoesterifolia is the worst.
The good news is that BGA is giving up too !
