I have recently purchased this Carolina Reaper plant a couple days ago. Up until yesterday i noticed that on several of the leaves near the petiole, the veins are starting to turn brown. The brown is only on the top of the leaves and is not mushy. The rest of the plant appears to be healthy, but seeing that I am very new to gardening (especially peppers), I didn't know if this was an early sign of anything serious. Any help would be greatly appreciated
