Need help with nutrient lockout

Its a big difference. I flushed yesterday with the ph adjusted to 5.8, but its too early to tell if that is the way to go. But in the next couple of days, it will be watering time for all the plants, and I really need to figure out, what level the ph should be with a Promix based soil medium. Where I bought the Promix, the dude said, to go 5.8, and nutient intake every watering, but only use 1/2 (10ml) as opposed to the normal 20ml per 8 litres of water.
I understand your more of a hydro guy, but if you know the answer to this riddle, please do tell.
:smokin:faceto27 Reviewed by faceto27 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
