Q.Why are my ivy fig leaves turning yellow
I do have my plant on a drip and as far as I can tell the drip is working.
First, two question - is there any sign of bugs (mealy, scale) on the leaves or stems; and, has anything happened lately to interfere with the light the plant is getting? If no to both questions, examine watering. Ficus can show both over and under watering with yellow leaves. To check how your drip system is working, you'll need to check the actual moisture in the soil. https://www.gardeningknowhow.com/garden-how-to/soil-fertilizers/testing-moisture-in-plants.htm
Once you figure out the actual soil moisture, you can make adjustments to your watering. Ficus pumila doesn't like to be kept
wet. This article has more information: https://www.gardeningknowhow.com/ornamental/foliage/creeping-fig/creeping-fig-vine.htm
