Plant withered in 2 days

I took this out of my grow room because they were male. However, in the course of 2 days the tips turned dark grey and the two plants completely withered. Ive never seen this before and was hoping someone would know what it is just in case its something that could affect my other plants.

Im growing in coco with added mineral ferts. no bottled nutes.

The other plants are fine and do not display any of these symptoms. The only thing i could think of is that i had them in a room little to no light for those days

What light did you have them under? Did you accidentally underwater? Do your other plants have white spotting on the leaves too?

Root rot? Just to be safe you should get it out of there, wash your hands and disinfect the area. Hopefully it's not fusarium.

3590 led cobs. Didnt water them at all but usually they can last until the medium dries a little

The damage started from new growth

No what light did you "temporarily" have it under? Not enough light with a wet containor could also lead to overwatering/root-rot like pecker is trying to point out.

No light cus i was gonna get rid of them anyway. I see, must be root rot then. Will check roots later to make sure
