Its under a grow light. I've been fertilizing once a month with superthrive. The humidity usually stays around 40% and i mist. ![5件中1件目の添付ファイル](https://images.getplanta.com/v1/resize/5tML9p3LA_CPa8flHvSiBFfoOnzla2LIrb5N0fsAXWc/RSQoJvtDRJKhFqTgRGlh9A.webp?size=large) ![5件中2件目の添付ファイル](https://images.getplanta.com/v1/resize/5tML9p3LA_CPa8flHvSiBFfoOnzla2LIrb5N0fsAXWc/MeAq2Co1R8GLDGa-xfrxXw.webp?size=large) ![5件中3件目の添付ファイル](https://images.getplanta.com/v1/resize/5tML9p3LA_CPa8flHvSiBFfoOnzla2LIrb5N0fsAXWc/x5VmEGpIQG--LuiW6mn2WQ.webp?size=large) ![5件中4件目の添付ファイル](https://images.getplanta.com/v1/resize/5tML9p3LA_CPa8flHvSiBFfoOnzla2LIrb5N0fsAXWc/uORwwbhfTbmDcX6SWiIgNQ.webp?size=large) ![5件中5件目の添付ファイル](https://images.getplanta.com/v1/resize/5tML9p3LA_CPa8flHvSiBFfoOnzla2LIrb5N0fsAXWc/WGM-v_rhTjia8uZqgCdHGw.webp?size=large) ## 10件のコメント ### Plantgirlyさんが2025-01-15にコメントしました The yellow dots might be some kind of fungal issue with the roots. I’d also check the roots for root rot. I’d let the plant dry maybe. I have a coffee plant too, and it’s the only plant that I consistently kill. I don’t know why this plant is more dramatic than all the other plants I own, but my coffee plant hates living. #### Abbiさんが2025-01-15に返信しました I haven't really had lots of problems with this one unless I'm doing something with it that I literally know is a no, like not enough light or miracle grow fertilizer. This is slightly concerning tho. I will let it dry out more and see if that helps, come spring I want to change the soil to a better draining mix and maybe put it in a smaller pot, the one its in was pretty big for it. #### Abbiさんが2025-01-15に返信しました Just wondering, have you ever tried propping them? #### Plantgirlyさんが2025-01-15に返信しました I have not! I neglect this plant because it is such a drama queen so I definitely don’t want more 🤣 ### Hollyさんが2025-01-15にコメントしました I’m no expert But Little squiggly thin white fibers… could this be… I hate to say it… spider mites? 😭 #### Abbiさんが2025-01-15に返信しました I think its dust, I was noticing it was really dirty and I'm gonna give it a shower. I hope it is anyways. I will def check it out more. #### Hollyさんが2025-01-16に返信しました Oh I hope it’s dust!!! ### Wolfen 🐺さんが2025-01-15にコメントしました With the dots, it makes me think a pest or fungal is going on. If you see a rabid increase, it's more likely bacterial #### Abbiさんが2025-01-15に返信しました I did check for pests and didn't see anything. I will try fungicide and see what happens. If its bacteria, what would you recommend? #### Wolfen 🐺さんが2025-01-16に返信しました I only have used physan 20 for antibacterial --- _Plantaコミュニティ (https://getplanta.com)。閲覧はどなたでも可能です。投稿、コメント、いいねをするには、Plantaアプリをダウンロードしてください: https://getplanta.com/download_
