Hello,
I have yellowing leaves on my plumerias (one plant worse than the other). The plants are in year 3 of growth. They are planted in a cactus mix and watered once a week and dry out in between waterings - it is now regularly over 100 degrees in Central CA. Full sun but not enough to burn the leaves. I fertilized in the spring with a balanced tropical mix, added Epsom salt a month later, and recently added a bloom fertilizer recommended for plumerias. There were some glassy wing sharpshooters for a few weeks but I trapped them and haven't seen any since. Could be some scale but it's tough to tell. What do the photos tell you?
Thanks for help
