My buddy's pepper plant continues to grow but everything is mangled looking including the stem. Any idea of what this is? No pests are noticeable and temperature outside is perfect. I don't think it's overwatered because there are other pepper plants in this garden box that look fine. No synthetic fertilizers are used just the occasional kelp meal and neem cake.
