This is an established plant which is flowering beautifully
I recommend pinching rather than cutting them off. Still, there is an underlying cause for yellowing of leaves. This article will help you to find out what is going on: https://www.gardeningknowhow.com/houseplants/african-violet/yellow-african-violet-leaves.htm
Have African Violets in a window in partial sun.
It's most likely powdery mildew. This article should help:

it. Now I detected that the large leaf is greying and I cut it down by half. I suspect that the plant was overly wet during shipment and the leaf got damaged, and now I have a case of BOTRYTIS. Your acticle mentioned to use Captan or Benomyl. Benomyl I cannot find at all on the web. Captan is available. My question is how to treat the plant since I cannot wet the leaves? Do I wet the soil? How does that work? Please help.
African Violets are very sensitive to any water on the leaves at all. This will cause what you are seeing now. You can try powdered sulfur as a dust. It may get rid of the issue without getting the leaves wet. Be sure to treat the other plants to prevent it spreading.
Most sources say to destroy the affected plant and treat healthy plants.

The Violet is 30+ years old and has been beautiful, possibly dying now. Very sad.
The fungus won't hurt your plant or you (unless you eat it). The spores were probably in the potting mix you used last month. They can be hard to get rid of but here are things you can try.
The plant is small and the outside of the plant's leaves bend over and rot. How do I fix this: the stems get long and lay down.
This is a sign that there is not enough light, and the soil remains too moist. Let them dry out pretty well between watering and do not let water come into direct contact with the leaves. Increase the light, or add supplemental horticultural grade lighting as well. This article will give you information on how to properly grow African violets:

I don't have any root grow and my african violet has become leggy. Read what to do but it says to use root grow. Can I get by without using it? And, can I just re-pot it in dirt? Or do I have to root in water?
This article says you "may" want to use rooting hormone. You can try it without. But below are some options you may have around the home. I would use potting soil instead of water.

I had an african violet on a south window for a few days when it got to 60 degrees. The leaves lost colour. What should I do now ? Thanks Balaji
It may have gotten too much light! They will do best in bright but filtered light.
This could have something to do with improper watering, as well. They are known to be very finicky, so knowing the exact environmental requirements of the flower will help.
