You also might want to wait a few minutes between adjusting your ph to make sure you get an accurate reading.
socialistpete Reviewed by socialistpete on . question and answer session...please Hi folks. I am new to hydro (coco) and have a couple questions. I am using Calmag because i am using R/O water with an initial ppm of 10. I am adding the calmag to 250-300 ppms. Now when i add the rest of the nutes do i add the desired ppm not including the 250-300? As in if i want the plants at 800 ppms does this include the calmag ppm? Another, as far as ph'ing my water. I just read in a mag that is is important not to have hguge swings in ph when adding nutes as this will cause Rating: 5
