yellowing leaves

hey peeps i got plants that just started blooming. is it okay if some of the bottom leaves are yellowing or getting lighter on the lower areas of the plant?

if its a tall plant i wouldnt be too concrnd, you can use some cfls for the lower portion if you are worried about them not getting enough light down there.

it is very few leaves turning yellow. im not really worried about light. i just heard that in the flowering stage it is okay for some lower leaves to turn yellow as a result of the plant devoting itself to budding. i am only 1 week into flowering and i already have lots of bud clusters
