Orange Tree problems
 

We have a 4 year old potted orange tree that we take in and outside as the
weather dictates. We left home for two weeks and had a froiend water our
plants. The light we usually leave on 12 hours a day, was on 24 hours a day
while we were gone.

Now we notice a couple of branches nearest the light have lost all their
leaves, blossems, and small oranges. Could it have received too much light?
Any other ideas?
The rest of the branches look alright to me, but no telling what will happen
in a few days.
