Looking at the pictures, you are only watering around a small area around the plant.
This is wrong. You MUST water the entire container so that you get decent runoff water and the entire soil is moist. Then wait until dry and water again.
Now you are just killing the roots from around the edges of the pot, as they do not get water. Meanwhile you keep rewatering frequently in the middle, which deprives the roots in the middle of the pot from oxygen.
You have fabric pots, so it's really difficult to overwater the plants, and you should be more worried about the soil drying out.
