Compromise and aim for ph of 6. I consider a medium hydroponic if it is INERT....and peat moss isn't. We DO need the Stinkster here.....
Weedhound Reviewed by Weedhound on . Need help with nutrient lockout Hope somebody can clear this up for me. I am almost 100% that I have nutrient lockout and that it is being caused by a ph problem. Sorry I don't have any pics to show, but from what I've seen and read, I am sure it is a nutrient lockout. I have 8 plants. 3 of them have burnt tips and edges and turning yellow. 2 of them show an Iron deficiency, and the other 3 look very healthy. The medium I am using is Promix. I water with regular tap water, the ph on the tap water is 7.2 to 7.3. This Rating: 5
