I wished you had submitted images to help with seeing what is occurring to your plant. Based on the information that you provide, it sound like a poor root system. You mentioned that you are not overwatering - assuming that in ground moisture conditions are ok, then you can rule out root rot. So I would think it might be poor root establishment. Sometimes this can occur when plants are overfertilized - too much top growth and roots are not keeping up.
If this is outdoors you might want to know that conditions in East TX is conducive for root rot related problems. We have seen high numbers of pathogenic root rot issues this year at the Plant CLinic.
