I suspect you already know that the increased lighting is causing it to turn away, its getting "sunburned". If you can, move it a bit farther from the light source, be that deeper or towards a corner, but dont force it to get more light, it needs to get used to the new lighting. You can move it closer as it gets accustomed to the increase in light.
