Hello dear orchidsforum family I am a newbie and I need your help. I have a Paphiopedilum for 4 months and the tips of the two leaves are dried out and turned brown. I thought maybe sunlight caused it and I changed its place. What might be the reason for that? I share some pictures of it. Another question is that also the leaves of my dendrobium Sa-nook are turning yellow and one of them started to dry but only a particular area. What could be the reason? They both stay in the living room and they take sunlight behind blurry windows not directly. I also share some pictures of it. Thank you in advance for your Help!
