Congrats with your new frillies, I hope you will enjoy them as much as I do enjoy mine =)
About the misting... Why use so much water when misting them. Misting means to me that I spray "some" water on my frillies and everything will dry up in 1 hour.
Other question... Why mist them 3 times a day in this periode of the year? Isn't it the time of year to provide your frillies a cooler dry periode? I supply them some water to drink in the morning and that's it for the watering for the day. Temperature I keep them at the moment is around 25 degrees celcius.
