I got this Stromanthe Triostar 6 days ago delivered from Amazon. It looked fine when I first got it. But yesterday I noticed the leaves are starting to curl and there’s a light brown spot starting on the side of one of the leaves. I have it under a grow light, the soil is still a little damp from when I first watered it. Is this happening to the leaves because it’s adjusting to the new environment or stressed from the shipping? Or am I doing something wrong, like not enough light or something? The first picture is when I first got it, and the second picture is what it looks like now.
