A lil while ago I got a neon pothos from a plant place and a couple weeks later leaves started turning yellow and black rings formed where the leaves attached to the main plant It was: - in a non-draining pot - in front of a grow light - only about 4 inches tall - watered maybe once a weak - never fertilised Does anyone know what could’ve happened? I looked it up and I couldn’t find anything that matched up fully with what was happening. The plant has since died, it has one leaf left but I don’t think it’ll last long, but I’m asking because I got another plant from the same place (a much larger marble queen pothos) and I’m hoping to stop the same thing from happening.
