Q.mexican blueberry leaves dying
My Mexican blueberry is in a large container and has some fruit but the leaves are dropping and turning brown. The pH is 6 and it gets 5 hrs of sun. What else can I do?
How have you been watering it and is it in well-draining soil? Over or under-watering could cause the leaf drop/browning you are seeing. I would strive to keep the soil lightly moist (not damp/soggy or dry).
Another reason could be rust which, in extreme cases, can cause leaves to brown and drop. More information can be found here: Cornell University PDF on blueberry rust:

The proper pH for blueberry plants is actually between 4 and 5. Here is an article on blueberry soil pH that will be useful:
