Foliar fertilization good for flowering woody plants

Question: We have a crape myrtle tree in our southwest back yard. It gets plenty of water, and I fertilized it last month with some Miracle Grow flowering fertilizer. At the time, there were some burned edges on some of the leaves and some yellowing. Now it is really burned on the edges of all of the leaves with yellowing. HELP!
