Hello,growing my first indoor grow using DWC,every time i test my ppm after i change water or from day to day the PPM counts go up and are inconsistant,i am confused why the numbers change in the wrong direction,following the schedule from the manufacturer to the ml,now on the other hand the plant looks good growing well but no intake on the nutrients,also the plants are White Widow Auto so maybe they intake the nuts slower or differently,Help is needed,Thanks

The same put in root riots and DWC.......Put in their root riots Jan...1rst.......I have not my ppm....HUMMMMM........
 
As water gets used and evaporates as well...nutes are left behind...
nutes are also in root mass....
Every so often run plain ph water for a day or two days then go back at feeding...or what ever your schedule is
 
Ppm going up means nutrient strength is too high, back off your dosage some and see if that helps. Following manufacturer instructions to the ml may be the issue. I've never ran at full strength, ever.
 
I run at 40-50% of listed label amounts myself. I understand Green nukes em with 3 times recommended dose I wish I were that brave!
 
Thank you for the info,i am only using 75% of the recommended usage(when i said to the ML i ment that i used the dosage recommended but on the low side) but only because i started out with 50% this is my 6th week and i have been upping the dose every week and everything was good but when i went to 75% that is when i started having problems,so i will go with your suggestions and flush it out with some fresh water with no nuts see if that helps solve the problem,thank you for your suggestions.:)
 
Hello,what do you mean by strip them after you feed them with the full dose 3 times,i have done defoliation on the 4 plants i have and i can see a big difference and in about a week they were so full of leaves i could not believe it,but now just taking off shade leaves,plants look great.
 
I feed three full times..then I strip/flush them...I use a stripper/ flushing product...
then plain ph water with calmag...then repeat whole process..
