Leaking radiator or front end

Hey guys first off let me state I'm a newb at fixing things! But am eager to learn. So I was attempting to flush my radiator yesterday. I drained the coolant out, flushed with distilled water, then added the zyrex flush cleaner along with more distilled water until it was full the bottle says to run your truck for 3-6 hours for a complete flush. Yesterday I noticed leaks but I figured it was just my a/c. I drove again today and noticed it was leaking again way more then an a/c ever should. I inspected the leaks and its leaking from both driver and passengers sides of the truck. Like both corners of the radiator. The peacock valve appears to be tight and secure. I have no idea what the issue is and I need help! There are no leaks on the Upper radiator hose... Could it be a thermostat leak? Any help would be appreciated.
