I am finding that each night when I test the pH it has always dropped down to about 5.3-5.4 So each night I add a couple of milliliters of pH Up to the reservoir and retest an hour or so later and it is back up to 5.7 or 5.8. Is this normal to have the water become more acidic due to concentration of nutes and waste as the water is consumed and evaporates? I've retested my pH meter a couple of times to ensure its accuracy so I kind of assumed this was to be expected?

Your nutrient strength is slightly too strong and your plant is drinking more water then nutrients leaving a higher nutrient concentration and lower pH. I would slightly reduce your nutrient concentration and attempt to find a sweet spot where your pH will remain most stable at pH 5.8.
