First welcome to the community. A picture would help a lot towards seeing what’s going on.
Photos will help us @headrush
Are you misting your plants under the light? It appears it may be damage from water droplets collecting on the leaves, and the droplets act as little magnifying glasses which intensify the light and burn the leaves a bit.
If this is the case, then stop misting under the light. Your plants should then grow out and be okay without further action.
