Sunburn. In S. CA I would give it mostly shade regardless, but in this case you moved it from indoors to outside without a transition period. Even in a sunny window, the light is far less intense indoors than outdoors, so the recommendation is to bring outside into shade and then move into a bit more sun gradually over a couple of weeks to avoid sunburn.

Yeah, that is the sign of too much sun. The leaves in direct contact with the sun get sunburned and turn a shade of yellow/off white but the ones underneath remain dark green. I give them (the ones I have in the ground outside) shade starting at 11am (if possible).

All I needed! You guys are great! Shade it is and gradual transition outside. THANK YOU Luis-pr and NHBabs. Shout out for your helpful comments! Very appreciated!

You're welcome. Also... I am not sure where you are but fyi... I too have Shooting Star and it is fickle for me winter-wise. It will "easily" loose flower buds during winter if the winter is mild and temps suddenly go below freezing for a day or more so be ready to winter protect it if lack of blooms becomes an issue in your hot SoCal location. Notice I said "if". Maybe in Zones 9-11 it will not be so temperamental.
