Hi everyone! I am still really new to orchids, and I need help. I have two paphiopedilums and they both have these markings on their leaves. Is it dehydration or something of the sort? Weather hasn't been too crazy lately and humidity has been I'd say around 70% on average. One of the orchids I got only a week ago and when I got it it didn't have these markings. Both are potted in bark with perlite. Info would be greatly appreciated
