    PPM or TDS newbie question

    I'm little confuse of those. I heard people say ppm should be at desire range. Let say week 1 at max 400 ppm. Does it mean my nutrient solution always at that range for whole week or every time a water that ppm range. I grow in soil and water plant 2/week. 2×400=800 ppm/week.Thank you
