As the photo shows,my Rhody has gotten very sunburned before I
had a chance to move or cover it so the last few weeks it's been
deteriorating health-wise,even though it's been moved into almost full
shade and kept moist..I have not used any additives or fertilizers. Any
ideas and suggestions will be appreciated.

The wilting and rolling of leaves is not sunburn, it looks terminal if
you are in the northern hemisphere. The browning can be sunburn or
winter damage.

The wilting and leaf roll can be one of the following:

Fungal disease
Lack of soil moisture
Too much soil moisture
Root damage from high root temperatures. If the sun hit the large pot,
it could have cooked the roots.

The actual damage is dehydration. The cause can be diseased roots,
damaged roots, or dry roots. Wet roots can cause diseased roots. High
soil temperatures can cause root damage also.
