I just noticed these rusty looking blotches on the leaves, I'm not sure whether it's contagious or whether they are caused by thrips either. Any idea what this may be? Thank you.

Your first photo looks like white flies, but Avocados get several type of mite too. Persea mite is the most common here. That's what the damage looks like to me. http://www.crfg.org/pubs/ff/av...
