OK I have been growing fora year now and because I now have Well water, I went and got a 8 stage RO system with a UV light.
So the Tap water I used before had a PPM reading of 120-150, and when I added the manufactures recommended nutrients per Liter my PPM was right on with the recommended PPM on the Manufactures bottle.
Now I have a RO system and the PPM is 5 before adding anything and when I add all the same quantities to the same amount of water my ppm is really low.
I did them side by side to make sure I wasn't making a mistake somewhere.
So for both I used the exact same levels of nutrients and in the same matching 5 Gallon Jugs, and I got these readings....
Tap water and Nutrients PPM was 1200-1300
RO Water and Nutrients PPM is only 300
Can anyone help me out?? do I add more to get my ppm up or leave it my levels.
