Please help with disease or nutritional deficiency or heat issue with my lemon guava
Guava None Given
My lemon guava which has been doing well thus far has suddenly started dropping leaves and fruit and the leaves have the appearance of the attached leaves. I live in Murrieta, Ca (it did get really hot a couple of weeks ago but has since cooled down) and it only seems like the lemon guava is affected. My strawberry guava is next to it and you can see what it looks like (although the strawberry guava is only just blossoming. I thought it might be low nitrogen which yellows the leaves so I added a little fertilizer yesterday ( about 6 teaspoons of 21-0-0 and 6 teaspoons of 16-16-16). I just wanted to check and see if any of you with much more experience thought. Could it also be the recent heat or is there something else I should look at? Any help would be greatly appreciated. Thank you in advance for any help that anyone can provide,
Jed
P.S. I did notice a couple of similar looking leaves on my strawberry guava but there were only 3 or 4.

It looks like nutrient deficiency (though I am not sure of specific element). Along with NPK you can apply recommended quantity of organic micronutrients like fish emulsion or rock dust.
Also it is subtropical tree and cannot tolerate high temperature. So provide shade during high temperature period.

I agree with Ravi. Yellow and strawberry guava thrive with some shading from taller trees and don't like full direct sunlight. It looks like they are out on a patio that probably gets full sun and they can probably bake in the California summer weather. I would recommend you move them where there is more shade or less direct sun. If your choices are limited, you need to be fastidious with watering them since they are like humid, moist environments.

I have a strawberry guava too, in Italy.
I knew that it likes direct full sunlight.
Should I move them where there is more shade?
I have it exposed to South, along a wall, so it has direct full sunlight from 10-11 AM to 18-19 AM during summer.
