I just want simple answers to this question based on your experience. Do your PPMs always drop throughout your grow as the level of water drops?
Im going to drop my ppm to 600 to test this out. ps - let me add that i've had exactly 0 nute burn on this plant.
Click here for a full explanation. It's written in a very simple manner. But it's not quite a simple yes or no answer so you do have to read the details http://forum.grasscity.com/hydroponic-growing/1198022-how-determine-what-your-plants-preferred-nutrient-strength.html
Nute burn doesn't mean your ppm is wrong. It means it is so far wrong it's actually damaging the plant. Growth will slow way before leaves start to die. Have the ppm at the correct strength and the plant will take up the solution at maximum speed therefore it will actually be taking up more nutes, it's just it will be taking up more water as well
I read your other posting. On my first grow my PPMs would stagnate with minimal ph swings. When nothing happened it made me think nothing was being eaten. What you wrote makes sense when you think of the water & nutes as having a fixed ratio. Atleast it does to me lol.
Its been a 4 day since I dropped the PPM to 600. And what I want to do reading today the water drop half a gallon and the TDS was 597. Sent from my SPH-L710 using Grasscity Forum mobile app
Sounds like you have the concentration correct now mate. The plants should be able to take up much more nutes and water per day now
