Now that i think about it, it might be your finishing schedule. Did you use a varathane oil based stain??? Using a water based top coat over a heavy oil based stain. When the top coat is applied, the oil in the stain seeps up through the finish and reacts with the acrylic causing a chemical blush. To prevent this, use a quick drying water based stain. If you choose to use oil based stain, seal the stain with a coat of shellac or lacquer sealer. This will provide a barrier between the oil and the acrylic. Proper drying time between the oil stain and finish coats is essential! The other cause for blushing is high humidity. Spraying water based finish in humidities of over 75% may cause blushing because moisture becomes trapped beneath the finish and cannot evaporate. You can prevent this condition by increasing air movement in the finishing area with a fan. All water needs to evaporate is sufficient air movement. You can also improve drying conditions by increasing the temperature in the drying area.
