It is getting down to about 58 degrees when the lights are out and up to 70 when the lights are on.
That is toooo cold, it shouldn't drop below 65 with the lights off and with the lights on you should be between 72-78 degrees. I would also say it's due to the cold, hope you have a way to warm it up in there.
Thanks for the help. I am going to get a heater and see if that helps.

Are you running your lights at night, when ambient temps are the coldest?
If you aren't, you might be able to avoid getting a heater by doing so.
Watch for higher humidity and any problems if any that may happen other than that it should be OK, maybe leave a small fan to circulate air slightly...
Plants need fresh air in the dark also, so turning all the ventilation off is probably not good.
Instead of a heater, which is going to use around 1500w of energy, you could raise the temp by using a large seedling heat mat.
There is a 20" X 20" that uses 40w or so, and it will keep the roots warm when the lights are off. If you keep the roots warm, the rest of the plant can tolerate the cold much better.
I have exactly the same issue you do during the winter months, and a large heat mat solved it for me without using a 1200-1500w heater.
Plus, you can use it under clones and seedlings when it's not doing heater duty.
