Will a hydroponic plant experiencing temperatures of 45-55 degrees be shocked by the respective temp of water?
will low temperatures in turn make the water with a bucket hydro system drop to the point that it shocks a plant that likes temperatures of 70-75 degrees?
My opinion is that this can't be answered with a simple yes or no, my apologies.
Without knowing what type of plant is being grown it's a gamble to say one way or another. A former coworker of mine was growing hydroponic lettuce a couple years ago inside an unheated building that (so I was told) was so frigid that ice would form over the surface of the water within the reservoir. This is less than ideal situation of course but they did pull through and keep in mind that lettuce can be very cold hardy. On another occasion I moved a couple pepper plants from an aeroflo system that was probably 75-80 degrees into a raft system that was just filled with tap water and was consequently around 55 degrees and that did shock the plants, though they survived and did well once the bucket of water's temp warmed a bit. The plant you are working with sounds more adjusted to warmer weather so it's likely to behave more like a pepper than the lettuce.
My recommendation is to visit to a pet store and get an aquarium heater. My concern with keeping the plants in water that cold is that if the temperature doesn't kill them their metabolism will be so slowed that growing just about anything besides the most cold hardy of plants wouldn't be much fun or rewarding. If that's not possible your best chance is going to be making the transition from 75 degrees to 45 degrees as gradual as possible so the plant or plants have time to acclimate with these new conditions.
Good luck
