if you start off with 100 ppm then if you add 1200ppm you got 1300 ppm. its that simple... you dont want you starting ppm to be as low as possilbe...

i use zero water filtration system and get 0ppm this takes a lot of guess work out of it especially if a problem occurs.. then add water ppm the nutes recommend... like standard is

0 ppm for seelings/clones for 2 weeks

300 ppm for early/small plant..

550 for medium/large

1300 for super fast growing/big plants...
