My Calathea Orbifola has gotten yellow at the edges with spots in between. It was very close to a grow light and I decided to move it a little further away so it didn’t get burnt. The plant came with the spot towards the tip of the leaf and that part has not changed. Grown in water which is switched once a month. Never used fertilizer. The plant is putting on a new leaf but it hasn’t fully grown. Any tips/help?
