Help identify please. Systemic fungus maybe.

Anybody know what this is? I scoped it and didn't see any bugs. A couoco other growers I know had the same thing and they believed it was a systemic fungus. It does look like it could be a fungus looking at the leaves closely. And it's spread to some of my other plants too. It seems to attack the new leaf shoots.

I can take some more pictures later if helpful

That doesn't look like septoria, I dealt with that for months before I figured out what it was and how to eliminate it

That could be some kind of a wilt, I've never had it but others here will likely know exactly what it is, better luck in the future

I am going with an infection dude.
Is it outdoor?
Blossom end rot, can happen aswell. But only if there isnt enough calcium. Which i think is pretty unlikely.
You have something serious going on at your root zone!
Do you have a long piece of pvc pipe, or one of those tools you can get, to take a sample about a metre down? So you can check the sediment all the way down the root zone.
Something is mushy and smell aswell. Do a soil perosity test with a piece of pvc. Just google the volume of the pipe and surface area you need.
You need to know exactly what it is first! Or you cant treat it.
Check your ec/ppm's aswell. First.
Good luck mate

Just check it all bro!
I promise. You need to know what it is first.
It could be ph
It could be fungal. Are there gnats buzzing around?
It could be algae. Check you water / reservoir.
If it is infection you need to have a really good idea of what it is. First
So you can effectively treat your problem.
Get an average temperature reading of your medium over 24hrs aswell!
Good luck.

Maybe some kind of wilt. I've had leaf spot septoria before and this is different.

Thanks for your input. It's definitely not a calcium problem. I test my soil at least every 3 months and I'm running calcium at 85% of the base cation saturation ratio. My EC is in the normal range for plain old field soil too. I would guess it's some kind of infection also, but what it is is the question. Aaaah the joy of growing in the tropics, ha ha!

No gnats or algae. pH is good too. The temperature where I grow in Maui stays pretty consistent throughout the year so I don't think that's the problem. Odd stuff

Thanks for the input everyone. If any of you are able to zoom in on the picture the dark purple parts of the leaves look kind of like some kind of fungus. It's just my intuition plus a buddy of mine said he believed it was a fungus when he had the same problem

Reason being.
If your containers or beds (especially beds), were consistently hot or cold id be sus! If they were, and i had to take stab in the dark id say-
COLD- fungus
Warm- algae
Large fluctuations can be worse too. Because its harder to narrow down which one it is.
When was the last time you did a flush?
If you're in a bed when did you last leech it?

My plants are in plain old field soil. I don't flush anything. I used gypsum, oyster shell flour, Cal-Phos, fish bone meal for the macros and the sulfate forms of the zinc, manganese and copper. I used Borax for boron, sodium molybdate for molybdenum and sodium selenite and sodium selenate for selenium. I have specific mineral ratios I aim for and I usually hit my ratios right on the head. Air temperatures have been between the 60's and 80's. Temperatures here on Maui don't change much throughout the year.

But actually I forgot to mention this started before they were in the greenhouse. They were in pots in amended Pro-mix when they got it. Thanks for the input!
