First of all - a picture is worth a thousand words, so if possible I'd love to see some shots of your plants that have the issues.
Secondly - the rocks on top of the soil in full sun could be burning your plumeria. There is nothing we can do about this information on the web that has been floating around since the 80's it seems, but we don't really recommend the rocks anymore. If you want the rocks, just make sure they don't touch the stem/trunk.
The drooping of the leaves could be due to being repotted. You could clip off the bottom leaves, just leaving the top 4 or 6 or so. Depending. I'd love to see pictures if possible!
