Totally posted on someone's thread on accident (I thought I was on a subforum 🤦♀️).
I have a baby plumeria and it got repotted about 2 months ago, it was growing wonderfully with about 5 big leaves and small baby ones starting. I repotted for more room and definitely some of the root got a bit damaged.
The plumeria was ok for a while and then started getting clustered spots on the bottom leaves. Some were silver/black tiny spots and some large round-ish black spots. The black spots would spread and become larger, the leaf then would turn yellow and curl up around the sides, the black would spread along the leaf spine, and finally the leaf started to droop and shrivel. The top leaves and baby ones were fine but as soon as a big leaf would die, the next leaf up would die. Now, even the baby leaves turned brown.
This is my first plumeria so no idea what to do. Neem oil has seemed to not do anything.
Photos show progress of the fungus/disease, missing a photo of the big black spots though. I completely forgot to take the bottom leaf photos, focused on the top newer leaf like an idiot 😅
