I can't figure out what is wrong with my baby. The leaves are actually turning orange in a v-shape. I water when soil feels dry down to the knuckle of my index finger. I don't have to water very often. She's in a large plastic pot with a saucer attached. The soil is general all-purpose potting soil. I use this with my other philo's and they seem ok. I've had her for a long time. She has done this off and on but now the problem is getting worse. I made magnesium foliage spray but it hasn't worked. Please any help would be greatly appreciated. I am so frustrated.
