Yup, they weren’t getting enough light. I fixed that for the most part, obviously they already stretched too far. But they recovered from that first mishap and then all of a sudden the dropping started.
Recently four of my seven plants have started dropping pretty badly. I don’t think it’s from overwatering because the soil has felt dry (at least a knuckle deep). Also don’t really think it’s under watering because they don’t seem to perk up when I do water them. I’ve tried changing the air flow...
