Can someone please help me understand this. I am growing in 50/50 coco & perlite using General Hydroponics Grow and Bloom for coco. I am currently in Veg feeding my plants 600ppm and feeding every 2nd day(one day feed, one day nothing, one day feed, one day nothing etc..). My plants are generally in good health a few purple stems here and there but overall good.
The thing that is bugging me is when I feed I'll hand water with 600ppm of nutrient solution with a pH of 6.0. Then the very very 1st runoff that comes out I'll catch to take a measurement and it will show me around 500ppm with pH of 6.2. Then I will continue throw a little bit more of the nutrient solution and take a 2nd runoff sample after a few minutes. Now all of a sudden it shows like 300ppm with a pH of 7.0.
When I feed I just throw in till it starts to runoff then stop but I know a lot of people say u must keep throwing till the runoff is the same ppm as the solution. I have tried to keep throwing liters and liters and liters of solution through till it eventually shows 600ppm at the runoff but then the next day it will be the same exact story 1st runoff is 500ppm then a little later it's 300ppm.
Can someone please explain what is happening here
