I just got this seedling delenatii for a week now. I grow it in temperature between 21c (70f) at night and up fo 31c (89f) during the day. Humidity is between 30% at night and normally goes up to 60% sometimes 70-80% during the day. I also run a fan close to the orchid but not directly to it And I’m sure that sunburn is not the problem. It was doing great and healthy the past week. today I saw this yellow patch on its leaf. Is it a disease or something I should be worried about. What should I do? So it’s time to expect it to die? I also have other 2 delenatii seedlings but they dont have these problems.
