I have some ladies under two 600W HPS lights about 18" from the tips. Some leaves showed burning so I raised the lights and added more ventilation.

One lady is losing her chlorophyll so I turned one lamp off and they seem happier.

The question is can you get too much light on a plant to cause it to lose it's vigor and color? Note, the leaves are reaching up for the light like they are happy.
