I just got this a couple days ago. When I got these, the stalks/stems were deep green. After the first day here, they started getting that brown tinge to them, almost like they are sun burned or tanned. They were in partial sun at their former location, and I put them into full sun here at home. Is this normal? Any idea's or suggestions? One pic is the browning , the other is the normal colors..I just got it 05/15..

This is more than likely sun-related. I often see the same thing when I bring my plumeria out of a shaded greenhouse into full sun. I try not to do this though. I typically will move them from the greenhouse to a part of the patio that is shaded by the porch after noon. Every few days I will gradually move the plumeria plants away from the porch and into more and more full sun. By day 7-14, those plumeria will be in full sun.

just move it gradually to full sun if it has been in part sun for quite sometime. It still looks really healthy though. Also good luck on your inflo you might see the first bloom in 2 to 3 weeks.
