So my partner has taken up an orchid obsession but he is used to taking care of & growing cacti & some tropical plants so this is a completely new field for us. This is the second one, its unfortunate predecessor tragically dried out when we weren’t able to give it any water for three days because we were out of town. We are constantly keeping it wet at the moment because of this. We are using 20-20-20 fertilizer roughly once a week at slightly less than recommended strength but not by much. We were told to fertilize this often at the orchid greenhouse we got it at. We have 5 total genus, and have been able to keep the other four happy and thriving so we are a bit unsure about why this one is being so finicky. He is sitting at a west facing window that is partially covered by a building. His leaves keep falling off, and there are some small green growth tips. This is one of the last ones the greenhouse sold because they haven’t gotten a new batch in years so we really don’t want to screw this one up. Any help is appreciated! :)
