Hello in this window there are 2 passion flowers, a passion flower hanging outside the window, an orchid, eucalyptus, jasmine, fictus, and lemon plant. All are doing good except one. The passion flower with the red arrow has started to yellow, leaves fall off, and it's constantly wilted. any suggestion? its the kind with the All purple flower. The other passion flower in the same window (behind the jasmine to the right of the photo you can't see it) is the kind with the white and light purple flower, and it's looking great.
