Uh! - Oh! Sounds like you need to withhold watering a bit. And only fertilize once a month at half strength during the winter months. Use the same fertilizer that you would normally, assuming that your formula has the Phosphorus (P) component as the lowest in proportion to the others two, N & K. If not, yu need to change it. A high P component will tend to burn your plant. The brown spots could be from overnight frost, also, if you had them outside. Here's my response to a fertilizer related question: http://www.bananas.org/showthread.php?p=9211#post9211

The pup may have taken off because the primary plant may have been subjected to some kind of injury (frost, over-watering, under-watering, etc.). If the potting medium is wet a lot, besides withholding water for a few days, thatch(cultivate) the upper surface of the soils as much as you can without damaging any roots. This will allow the soil to be aerated. When the outer upper 1/2" of the soil is dry, then water as usual. If the upper surface remains wet for a few days, do not water again until 3 or 4 days have passed.

If the potting medium (soil) has dried out at one time, the way to ensure that you do not have pockets of dry medium is to imerse the whole pot in a container of water for at least an hour. Oftentimes, when the soil gets dry completely, and then you water the pot, the water will be absorbed at the surface about a half an inch and then roll down the sides, making it appear that the soil is saturated. In fact, only the upper surface and a layer of soil around the side have been wetted. The volume between those layers are in fact dry because when materials are very dry, the application of water is repelled initially by the materials, until the materials are enveloped by water. Otherwise, water will just run through.

Assuming that your brown spots are actually closer to black spots, it is a definite sign of over watering. If they are in fact light brown spots, it is possible that the leaves were exposed to very bright sunlight when there were water droplets on the leaves. Those droplets act like magnifying glass concentrating the sunlight on the leaves causing severe sunburn. This is why most experts caution gardeners not to water plants in the bright sunlight, unless the water is applied directly into the soil.

Any chance you can post a photo of your plants to show their condition?
