Need frequent watering. The soil can dry out and when that happens it prevents plant from feeding thus you see some leaves turning yellow in the process. The plant is sucking the nutrients from the leaves to survive. I wouldn't trust the water meter completely. Use the lift method to determine if watering is needed.

Please do not water the plant with warm water. Cold water contains more oxygen per volume and with soil grow it can use more oxygenated water.

Great work on cleaning out the yellow leaves. Looking at the nutrient chart and feed the plant with the proper strength at this stage is all you can do. Remember not to let the plant go bone dry. Over watering would be watering daily. Do it every 2-3 days for soil should be ok. If your room temperature is hot then frequent watering is needed.
