I have a Oro Negro Avocado tree in SW Florida. I am by the coast on a salt water canal and the tree is about 100 Ft from the canal. The leaves started turning yellow, with rust colored veins, right before flowering. A bunch of leaves dropped during flowering. Now that the flowering is over I do have some baby avocadoes and new leaves look fine. I only have a few yellow leaves left. My concern is the rusty veins may indicate some sort of soil deficiency? Can anyone tell me if this is the case? (leaf photo included)

We didn't get photo.
Are you giving it avocado fertilizer ?
Frequent shallow waterings a couple times a week when weather is warm, or top 1 to 2 inches of soil dries ?
They are susceptible to root rot, if soil is not well draining.
Ground, extending a good 6 feet beyond drip line, should be clear of any vegetation, even grass. Feeder roots are, in top 6 to 8 inches of soil.
So, no digging. Just shallow cultivation of top couple inches.

Is the soil in your yard high in salt? That close to the canal, I can't imagine its not.

Thanks for the response. Yes, we gave it Avocado/Citrus fertilizer in March. We worked it into the first few inches of soil, a few weeks before flowering. The soil is mostly sand, so I would think it drains well. It gets watered twice a week for 45 minutes or so as it's on a sprinkler system. It's been a wetter winter here though this year, so that might be part of the issue too. It does Not have the 6 ft of clear ground around it though, and that will be an issue for us, we never heard that it needed that much space from the nursery guy who sold us the plant. Will have to take a look at that now. Yes, I did read that it has shallow roots, I also think that I should change out my current red mulch to a more organic type of mulch. Oh well, live and learn...

You needn't clear the ground around your tree. The reason for clearing the ground is to keep the tree from competing for nutrients and water. But avocado trees are so big, that eventually, you will have an area about 50 ft across cleared of all vegetation. I grew avocado trees in the middle of my perennial garden in CA and the plants around the tree did not slow it down any. I would keep vegetation from growing right against the trunk as that will cause root rot problems.

One other thing I forgot to mention.
When I did my research of avocado care.
It said to deep water them, twice a year. This rinse's salts from fertilizers, etc. Down from root zone. 👍👍
