Indoor plumeria brought outside going soft
I got 5 new small plumerias from Home Depot yesterday, and they showed no signs of rot or softness. They were kept indoors there, but I thought I could still bring them outside. Now today, within 24 hours some have wrinkles and are soft, it can't be rot. I put them in half sun like it said to on the tag. One of my JJs did this when I bought it but it got root rot because I was recommended to water it more, and is now recovering. What could it be? Thanks.
