DWC in 1- 5 gallon bucket together currently
Plants are roughly 2.5 weeks old from seed.

These were bagseeds so I germinated 3 not thinking all would pop so I was going to let them run a couple weeks and only keep the one I felt was best.
Problem is roots tangle up so when you kill two you'll have a bunch of dead roots.
Your water temp is way to high,your pH is too high,5.8 ish is good.
You'll need some bleach or h202 in your water.Root rot is knocking on the door.

Water chiller or maybe try an ice pack. You may want to start with an easier method. Soil maybe?
DWC has parameters that must be met otherwise you're doomed.

Well I’ve moved the grow tent out of a closet so better airflow hope that allows cooler air and water temps. I e done dwc before with great success just haven’t since 2018. I’ve gotten ph and ppm reset to roughly 6 and 300 respectively. Temps are coming down I will check back in a few hours.

If you run an antiseptic res using pool shock (my preferred) or H2O2, you don't have to be concerned with temperature. Beats the hell out of buying a chiller or constantly handling bottles of ice.

Are you using tap water? If so what's the PPM? What nutes you using?
Yes tap letting it sit for a day or more to get out chlorine. The ppm of the Rez is about 300. The tap water is about 100 ppm. I’m using Canna Aqua VEGA A & B

Is it good tap water, like would you drink it? Calmag? I don't know nothing about your nutes so don't know what's in them. If your using oxidizers and not bennies do you have to let it sit a day? The chlorine will help disinfect some I would think but idk for sure.
