less often... but more water when you do. Let the container dry out all the way to the bottom... zero water weight, before you water again. When you do water, water slowly to runoff... saturate the soil... Use a lot more than 1 oz.
When you water too often, the water you give drops down to the bottom due to gravity. If the plant has not used all the water, when you come in again and water because you think the top is dry, that water again drops to the pool of stagnant water in the bottom, adding to the water table. If you do this consistently, even using only 1 oz, you will end up with the lower roots sitting under water all the time. Submerged roots can not get oxygen, and eventually they shut down so as to protect themselves from the flood.
This is what your leaves look like. The lower roots are in trouble and the plant no longer can get the nutrition it needs, so it is starting to cannibalize the leaves.
Let your containers dry out, so dry that you will think you are killing them. If your human senses can feel water weight when you lift it up, it is not yet time to water. Establish this wet/dry cycle, and watch as the roots finally wake up and start growing again, and how the cycle time between waterings will go steadily down as the roots get stronger. Right now you are probably at a 3 day wet/dry cycle or even more, depending on how shut down the plant happens to be at this point. As you repair this damage, that time will finally go down to 1 day between waterings, and at that point it will be time to up-pot. Figure this problem out now, so that you can start getting some rapid growth on these plants.
Please read my watering guide... it will help to explain this concept of the wet/dry cycle and when to uppot.
