help needed with fruit trees (pix warning)

[Gold Metal Flake]

My apple, plum and lemon trees look sick. I have been spraying with an Ortho fungicide but it does not seem to be helping. I was watching some fresh blooms on the apple tree and they were healthy looking but now they are starting to turn brown like the previous ones did.



A close up of the blooms:


Another branch:


Underside of a leaf. Spots?


My plum tree has curling, drying leaves:


My lemon tree has yellowing, curling leaves:


My lime tree is dark green and lush and is heavy with fruit but the lemon tree dropped all of it's blooms. The plum tree had fruit a month ago, but has not bloomed since. No new fruit on the apple for over a month. My dwarf orange looks about like the lemon.

Help my trees!

1. Cedar Apple Rust?

Do you have any cedar trees within a 1/2 mile or so? They need to be in the vicinity to get this fungal disease.
You can also contact your local extension office to see if they have any ideas. There are probably diseases common to your area that they are familiar with, plus treatment methods.
I don't know much about the plum or lemon trees.

2. I have cedars within 20 feet.

3. You should be able to verify

By sending a sample to the state extension service. Once you know what it is for sure, you can develop a treatment plan. Or maybe find resistant varieties that aren't susceptible.
