Welcome to RIU
hello,
I’m just using 80% Empire Builder soil 20% coco as medium.
Stays around 70-75 degrees
Blueberry Muffin Autflower
Light 20 hours on 4 off
I just topped off pot with empire Builder soil yesterday to see if that would help and didn’t. I have fox farm nutes but haven’t used any in a bit because it seems to get nutrient burn. I used 1/8 of recommended amount.
I’ve consistently ph water to 6-6.5 but soil/coco blend but soil ph meter shows 7.2.

It’s a mars hydro ts -1000. It says it puts out 150w and I have it at half power, the light is 27” from plant.
POTASSIUM:

Excess:
  1. Root zone is acidified
  2. Causes Calcium, Magnesium, zinc and iron deficiencies
    1. Newer leaves develop interveinal chlorosis
    2. New leaves grow thin blades
    3. Leaf tips and margins burn
    4. Less internodal space
    5. Lower leaves curl develop spots
I'm really not great at this, but it seems to be fitting.

I'd water them without nutes, mbe add a bit of molassis, in case you're really acidic in the rootzone for some reason, that should help.
See how the plants react. You can always go back to goin berzerk with nutes if it doesn't work and im talking out of my a** here.
Right?

Your stems are red right? With that and the brown leaves you posted (P def) I would say you have pH issues or lock out from an excess nutrient, potentially calcium. Are you giving cal-Mag?

In the future don’t mix coco/soil. Choose one or the other.

From my experience PH issues aren't really becoming apparent unless you do something significantly wrong.
The soil usually handles PH swings pretty well.
With that being said, I have no real xp with coco or any mix of both.

Optimal PH should be around ~5.5-5.8 for coco and ~6.2-6.5 for soil roughly.
If you're at 7.2 actually you could try a more acidic watering without any nutes and see the development.

Also: I'm with Nutty here, keep it simple!
Question is: Are you be able to control a mix better it to reap ONLY the benefits? This would require specific tests and documentation in my opinion.
So I'm not a fan of the 2 pills must be better than one logic here for that reason.

But, hey GL with it and if you stumble upon a holy grail -> I'm deffo interested in hearing about it.
Cheers.
