Thanks.

I do have a PPM meter, I have been making charts to watch how it moves up and down, (Always down at the moment), I have been topping up with plain water which always lowers PPM and raises PH, but I have also been couculating that into my chart reading.

This time Using Canna.

I started off with an EC Rating of 1.3, and although it did slowly drop, I think that it was too high, leaves started to curl at the ends.

I'm also working on using rain water, but I am still wating for the requred PH ballencing chemicles. I gess I may find it easyer to control that.
