My pothos has been losing leaves towards the base of the plant. Many currently have yellow marbling, assuming they will also be lost soon. Does anyone know what this might be from?

The plant is near a south facing window and gets bright indirect light most of the day. Watered once a week until water comes out drainage hole. No recent events like repotting. I did have a grow light nearby for a while towards late winter but haven’t been using since seasons have changed and we get more sun in this room, could this be from that?

I’m not aware of any pests and it is in a houseplant mix from my local plant store. The leaves up top are still looking good but I’m worried this will just continue upward. Finished

Bottoms leaves on this pothos are starting to get yellow spotting while top leaves look healthy. It gets indirect bright light all day from a nearby south facing window but I also have a grow bulb in a desk lamp pointed at it. 1x weekly watering until water comes out drainage hole.
