spots on my ilama leaves

[buddyguygreen]

Its in morning sun with afternoon sun mixed with shade from the bigger trees.

Just wondering what it could be from

[Guanabanus]

Potassium deficiency.

Thank you, Just bought some Earth Juice Meta K

Is that a seedling or a cultivar?

[Radoslav]

I had it on my Ilama seedlings too. After some time leafs withered and dropped away. I thought it is some kind of infection  ,  so I removed those seedlings, now I see that there was a chance to save them.  In case that it was Potassium deficiency.

Its a seedling

I made an another attempt to grow  ilama seedlings, but once again I see white spots, which are turning brown with holes. Is it potassium deficiency? I see it only on Ilamas, another annonas are fine. They are indoor.

I has the same problem with my Green and Red Ilama seedlings from different sources.
It's not disease or fungi. I notice high Ilama leaves sensitivity to sunshine (even some filtered) and to low humidity. Suspect some nutrition deficiency, but not Potassum. I'll be experimenting with additives of the clays and minerals.

[Radoslav]

Humidity has some influence, because when plants are outdoor symptoms greatly reduced, most likely by higher humidity.

Radoslav,

I agree, I strongly suspect the small white dots that you are talking about might be caused by low humidity.

It has occurred on both red and white ilama seedlings from different sources, where the leaves would get these white spots and then fall off. I noticed that it was only when I had them growing indoors, but as soon as they went outside in spring, they grew just fine. I have lost a few seedlings because the leaf drop was excessive. I am not sure if there is a deficiency or pathology associated with it that might explain it. None of the my other annonas have this symptoms.

[Guanabanus]

It was about the small black spots in the first picture that I opined "Potassium deficiency."  About the white spots, I don't know.
