We have a 2 year old tree in Camarillo, CA where the soil is clay-ish. Tree had some good growth this last year but not as much fruit compared to year one. We had some leaf miners in year one which we treated for, as well as some aphids. Went just away for a 3 week trip which end up being hotter than usual (80-90 degrees), but we have it on a drip irrigation that adjusts automatically. Checked the soil and it's damp.

Came home to see a lot of leaves dropped and yellowing. Read that temp changes can cause leaf drop but I'm suspecting iron deficiency, would love advice to help figure out whars going on. Alao noticed a few areas where prior pruning cuts were turned black on the edges. Any advice?

Hi and welcome to NGA!

I hate to be the bearer of bad news, but it appears you have Citrus Greening Disease which is spread by insects. This disease decimated the citrus industry in Florida and now it's doing it to California. There is absolutely nothing at this point you can do for it.

I agree with Xeramtheum. Sighing!

Here is some closer to home info for you:
