Need help all the leaves of my phal got sunburned. Left it in the East window of our porch it has no screen. It gets direct sun until 10am. I forgot to bring all of my Phil inside when we left for 2 days.the other 4 is OK this one is the worst. Anything I can do to save it? Should I cut the leaves? I cannot post picture still trying to figure out how. I am in the Philippines.
