What Ppm Is Ideal For My Plants?

[mcaveman]

My PPM and ec are zero with my R.O. water, I normally add nutes and adjust PH, what should my ppm of my water be?

Did you want to enlighten us on size/age of plants? Nutes to be used? Pictures? Lighting?

12-14" tall. 1000w light, 3-4 weeks old and just started the fox farms nutes at half strength, these are in depot organic soil , this is my first grow.

Depends on Sativa Dom or Indica Dom in my opinion. Sativa at that age I would do 500-750ppm, Indica Dom Its more like 800-1000ppm on a .7 tds scale. That's just my experience, Sativas get nute burnt a little easier and don't need as much. Indicas can take more abuse, and require a little bit more nutes. Hope that helps a bit. What are the genetics?

Btw never used as salty of nutes as thAt so the ppms may be more or less.
