I'm following Planta's watering schedule for a pair of poinsettias but it feels off. One of the two Plants is dying and soil is still very wet, planta wants me to keep watering. Using the light monitor, it said I had partial sun, but light monitor seems to just be directional and not take direct / indirect into account or look at the actual light quality. Maybe it's not getting as much light as Planta thinks? Other thing could be soil type, which I don't know. Any thoughts?
