PH water and nute mix for pro mix or "soiless mix" at 6.3 its best... was told this from a very good grower from the old advanced nutrients forum... (damb it all for shutting it down)
saltypimp Reviewed by saltypimp 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
