stinkyattic,

Thanks for the advice - I had avoided tap water because the water here is extremely hard and I was concerned about excessive Ca++ and Mg++. I have a softener but then the water would be Na+ laden. I'm thinking that I may start using a 50/50 blend of tap and distilled - or just stick with the distilled and add the CalMag plus.

Regardless, as per your advice (and weedhound's) I'm ordering new nutes now (will try the Canna Aqua A+B).

I'll post picks of the progress -- thanks again!
