Thanks for your very kind message. It brought a smile to my face. I respect your "humble opinion." I am no expert, so I could be wrong. Here are the facts that I have.
1. The leaves don't burn and turn crispy around the edges except when I first take my plants outside. The leaves were not brown when over-wintering.
2. I check the soil moisture levels in the plants daily with a moisture meter. If the plants are too dry, I water them. If they are wet, I leave them alone.
3. When I put my bananas outdoors for the spring/summer, I increase my watering schedule. The large plant in the picture gets watered everyday in the morning, and if the day is particularly hot, in the evening too.
This is why I feel that the burning around the edges has something to do with being exposed to sunlight after being over-wintered indoors. The crispy edges may have something to do with excessive transpiration, but I have not a clue.
By the way, please look at the large leaf emerging in the background. Notice that it is perfectly fine with no browning around the edges. Also notice that the plant is indoors in the picture due to another cold snap. The plant has been inside for about 4 days. 
Today, the temperature warmed up again, so I put it outside this morning, now look at the leaf in the background. I tried to photograph the plant from the same angle. Sorry that it is night time. I work. If the plant looks a little funny, it is because it rained earlier.
The leaf that was perfectly beautiful this morning is now burnt around the edges.
