You can turn the grow lights off and use a regular white room light like what is in the ceiling or put a table lamp with a white bulb near by.This is water & light reflection
If you take the photos without the grow lights turned on the photographs are more likely to show the true colors of the leaves and of any spots. It also makes it easier to see if there really is an insect problem or not.
It will not hurt the plant to turn off the grow lights for a few minutes that it takes to get the better quality photo.
