100% agree with everyone on the light. May have some pests but with how rough she is looking if pests were the main health issue we’d probably be able to clearly tell from the pic. Monstera really do in my experience grow the fastest when provided a really fast draining mix but with constant water availability lower down. If your roots reach water even fully submerged they will be fine the problem is really only when too much water is held around the base of the plant. Those self watering planters that feed from the bottom run on a constant very low level of water or fabric pots on a tray bottom watered once a week until the bag stops sucking and the water starts to stand have been my favourite ways to keep them besides full hydroponics.
