I recently planted out my Thai Dragon in zone 6b. It was hardened off nicely for a good month and was looking great. I planted it out about two weeks ago. Lately it's been looking pretty bad. It has a bunch of new growth but the existing leaves aren't looking too good.

Any ideas what the problem could be?

This raised bed it's only 2 years old and is using last year's triple mix. Last year I had no issues at all, everything grew incredibly well. I should also mention that I have another Thai dragon plant directly beside this one that looks wilted and dead. It seems to get better at night, but the sun seems to make it wilt hard. Both plants looked very healthy prior to me planting them out. Does anybody have any ideas or suggestions? Really hoping this isn't a fungus that's gonna kill my season.
