k, couple of things:

First, who's that girl in the picture? Second, your meter could be off so make sure its calibrated. Use EC readings instead of TDS. TDS is actually EC in micro siemens X 600 - 700. As such certain nutes manufacturers will tell you different TDS readings based on the most popular meters. BUT, the EC will always be the same!

So I assume what you are doing is adding the recipe and not getting the reading on the recipe label. If all else is accurate than don't worry about it, heres what you do:

Mix up the batch and feed it to them. Check the EC for a week, every day. If the reading goes down, increase your nutes on the next run. If your nutes are going up, then it was too strong for them and mix less next time.
herbie the love bud Reviewed by herbie the love bud on . Directions on hydroponic nutes I just did a bucket of nutes, and with only 2 gallons of distilled water and the appropriate nutes I test the water 2 hours later in the bucket still and my numbers are half of what they should be. My nutes say the PPM should be between 1000-1200 and I am only measuring 520ppm? Any idea why its not where the range should be and since its 3 part and a supplement of golden nectar do I just add more of all nutrients or some of certain ones or not? I want to be at the PPM per the Rating: 5
