Have you tried putting a fan on them?
Putting a little space between your floor and the buckets (some type of spacers) will allow air-flow to reach the bottoms.
Decent size floor fan pointed towards the bottom.

What's your average room temp?
when I mix up my nute,ph water for my tub I make extra gallons and put them in the fridge... Then I pull that amount out of the rez in the morning, add the cool stuff and put the warm stuff back in the fridge. I just keep swapping them out. Adding bottles on top of that should help!
