Don’t forget to bump the ph to enhance cal-mag absorption.

Honestly I don’t think is the ph problem, maybe my ph pen’s problem, I have 4 ph pens 3 from blue lab. All different results when I test the same solution. I was confusing all these years. Every time I may thanks to God if the solution ph will literally stabilize at 5.8-5.9 even 6.0. Too much work to ph down the solution.

I am not saying yer pen is off. I am saying you are running quite strong food @6,0 which may cause pH to drop. I do not see any calcium or magnesium issue. What kind of nutrients you use?

What pH is your water to begin with? And are you adding a lot of pH down?

I use RO water. my water ph before add nuts is 7.5+. After add nuts around 6.8. Add 0.2 ml ph down from Advance Nutrition to ph 6.0

I'd cut out the pH down, which is probably phosphoric acid and see if it improves. Or get a good pH soil probe to see what's really going on.

Medium pH Correction (Soil and Coco)

Checking and adjusting the pH of your root zone in soil or coco is a very important part of growing healthy plants. Often you will notice nutrient deficiencies despite the fact you know you have provided an ample feed at an appropriate pH level. When this happens it’s generally either...

I have two soil ph pens from blue lab and I calculate the P ppm from PH down within the P2O5 to get a better NPK/CA/MG ppm ratio every through Excel
