Just reported my philodendron sodiroi last week and treated with neem oil yesterday (as a preventative, no pests so far) and the next day I found the bottom leaves a neon yellow!! Have been watering once a week, last water was last Sunday, about 4 ft from a window, has a grow light as well.. it does not look like the kind of yellowing you get from over watering.. and happened overnight! Anybody seen this??
