Fukien tea disease?

[AussieBonsai]

Hi all. Apologies if this has been covered, but havent been able to find a similar example on the threads. My Fukien tea is showing ruat coloured markings on its leaves. I've adjusted watering and dont believe its ferts related, and so does anyone recognise this as a fungus or disease? The picture below hopwfulky shows the progression. I've looked at the roots and dont see signs of rot, which I thought could have also been an option?

Here is another photo which shows the problem better. Any help is much appreciated!

I think I have found the culprit.. Neem Oil. The mix may have been to strong. At least thats all I can guess at

The distribution seems to match.

Sorry, when I saw this thread Friday I was just like...."yeah...sure!", But figured it was regular Fukien problems.

Did yours already do the whole, drop all it's leaves thing?

No, the leaves havent dropped, which I think again points to foliar burn. Bit of a pain, as I seem to have never ending issues with this species, even though I'm in the tropics myself

Why did you apply neem oil?

Why did you apply neem oil?

Aphids. Neem oil is the go to product here due to its availabilty and very widely used

Aphids are easily killed so a low dosage should be fine.

No dosage works too!

Blast em with the hose....into fire!

You are not alone.

If you applied neem with the sun out.......no bueno. Magnified.
