Which Full spectrum LED grow light (Root Farm brand) do you have?
How high is it above the plant?
What is the temperature at the plants position?
What is your photoperiod?
It looks like the plant went from low light that it was accustomed to to very high light which sent it into a sulk and lightburned it.
I have a generic response when a Sundew throws a major hissy fit like this, regardless of cause.
1) Unpot, Rinse the plant and roots well, and Repot into a peatmoss/perlite mix.(2:1 - 1:1)(I've had better outcomes when I use peatmoss instead of sphagnum moss mixes)
2) Bag or dome the plant for 2 - 4 weeks until it is showing good healthy new growth and it is producing lots of dew. (This reduces transpiration moisture loss from the leaves and reduces stress on the plant until its roots establish good intimate contact with the new medium.)
3) Bottom water by tray. Water level should be just below roots. (When repotting, I leave the roots one inch above the bottom of the pot)(Pour in one inch or less of Distilled, RO, or Rain, water. Let water drop to a quarter inch before refilling.)(TDS under 50ppm, TDS meters are an inexpensive necessity.)
4) I set the lighting photoperiod to match its origin area (for inside plants) or my local area (for outdoor-bound plants) I use astronomical light switch timers or Raspberry Pi s to simulate sunrise and sunset times for the desired area. For a Cape Sundew, I'd set it for a latitude of 33.5797° (N) and my local longitude. This gives it the seasonal variations it expects to see and helps encourage flowering.
5) I set the lighting brightness to match outdoor brightness under open shade. (about 25% full sunlight brightness)
6) I grab a coffee and a book and come back in 4 weeks to check on it.
7) Use a mist bottle for spraying Nepenthes and a misbehaving, barking, growling, Maltese dog, not Drosera.
As always, this is just my 02¢ worth.

Wish I had known that earlier. Then I wouldn't have wasted money on giving them silica sand...
