Leaves turning dark purple

[alawn]

The leaves on some of my peppers are turning dark purple. I have heard this is from the light. Is this true? They look healthy other than the color. They are not the types that always turn purple. I have mostly 6500k light. Should I just leave the lights alone or should I move them/change lights? If they grow fast I don't really care what they look like.

Its not a bad thing, its just to do with blue spectum light. Try doing a search here too, its a popular topic this year

I had the same problem. I added some Start-N-Grow fertlizer...on the light side...and within a week the purple was gone and the plants were growing.
