plants leafs are turning white and dieing

I have several plants the leafs are turning white and falling off my hibiscus, bagonia(?), bogavilla and also my christmas cactus. Please help

 

Have you recently put these plant into full hot sun, because it sounds like sunburn to me.

 

I have recently move and have put them on the deck, i did not even think about them getting sunburnt :{ I just thought they would be as happy about being out of the apartment as i was.

 

yeah the leaves that are burn will probably fall off, or them may just heal over time, next time slowly climatize them by placing them in dappled shade first before the full sun.

 

Thank you,
