Two things going on here. Leaves have been either over-watered (my guess) or unederwatered with heat stress. The other factor is the "swirlies". That occurs when you change the orientation between the plant and the bulb. The leaves will try to track the light source and remain pointed towards the light. Moving the light source produces the swirlie effect and is that easy to fix -- don't move the plant.
Good luck, BigSteve.
