Hellllloooo
I've been using mineral water for my plants which has a background of 0.1 EC & mixing my nutes to total strength of 1.5 EC.
The intention was to filter my tap water which I tried but it still had an EC of 0.5 (same a pre-filtering).
I take it if I now use a background EC of 0.5 I weaken my nutrient strength to 1.0 (as opposed to the 1.4 I was using) so I still get the same total EC strength of 1.5?
Cheers,
B1unt
