Hello It looks like phosphorous def. Not really sure of all your temps . RH, Soil, ect.. but it is kinda bluish what would lead me to believe it's Phos.

I believe your seeing a blue light for a led it’s nothing but green yellow and brown on it man

Not sure how what I’m taking about clearly CANT be seen cause a “blurple” light is just effecting it isn’t it

Hmm, OK. Of course I see the issues with the leaves. But the natural color of the leaves can't be seen properly under any color light other than natural or white.

I'm obviously of no help but good luck with fixing the issue with your plant.

Now we can't even ask for better pics lol.
I'm beginning to think a good % of the blurple growers never look at the plant when the lights are off.
A con about blurple that is never mentioned is that people who learn to grow with them are probably not learning to read the plant the way others do with other lights.
Hate filled rant over lol!

Fox Farms just has too many problems. I think its more of a soil for advanced growers during those lazy times

I vote Mg deficiency...but whether it's locked out...or not enough was given...not a clue.

IMO, your leaves are expressing an advanced ph lockup.

Pic for reference. Moderate pH lockup

FFOF is notorious for having a low or unstable pH and its generally advised not to pH water for living soil.

IME, FFOF works best with plain tap (suitable tap under 200ppms)

Tange,
I would like to know more about this. Are you saying that the FFOF will create a situation similar to a toxic salt build-up in coco? ((coco grower here). And that this is what you feel is causing his problem?

So a runoff ph might be...Oh say 4?

Some say its due to a lack of quality control but I think the acidity is due to the organic matter decomposing and releasing hydrogen ions.
Nutrients containing ammonium (urea) will drop the pH even lower. Probably why we see so many issues of lockout with growers using bottled nutes on heavily amended soils like FFOF

Thanks...The nutrient thing...I think most respected manufacturers try and balance the urea with other non-urea N sources as a means of buffering ph. The problem comes when you overload the soil with it. The newb desire to do more...make it grow faster. Pour more on.

And I can sure see why the stuff has killed so many seedlings.
Cheers,
