Nute burn or fungus!

[Lilnuggs]

Good day all, I have this one plant that I thought had nutrient burn, flushed it with Ph water, and reduced nutes for this girl only as my other 2 plants are loving their current mix, but issue isn’t going away.
Leaves are yellowing, crispy tips, starts at bottom, and works it’s way up, also noticed cracking in its main stem that doesn’t look right when compared to my other 2 plants.
Any insight always apreciated.

The leaves look like N toxicity but that stem ... ? Looks like something ate a hole in it & is living in there. Have you checked with a loop or microscope ?

No, I haven’t looked that closely, how long does it take nutrient burn to go away, should I just water with plain ph h2o?

I flushed it and started using cal mag about 2 weeks ago, I guess I will just wait and see.

I am pretty sure you got a fungal infection.

It’s an outdoor grow, so it wouldn’t surprise me, I could pick up some safers fungal spray and see if that helps, this plant has been my problem child from the beginning.

Would the infection be right at the main stem and in return blocking nutrients from being taken up? Now the plant is just slowly dieing?

Possibly, I just noticed that today, never seen it before, hopefully it’s salvageable.

Yea I overlooked that stem damage pic at first.

I'd stake up the two branches next to the stem damage- fungal or not, when the branches get heavier, the cracking will get worse.
They actually look like stress cracks to me.
