Spots on my leaves

I have a white widow plant in Bud phase but over the last couple of days I have been noticing some brown spots on a couple of the leaves.

I'm not sure what it is or what to do about them.

I'm using a Hydroponic water farm with drip irragation I'm also using GH nutes

The plant is in its 10th week from seed growing it has a healthy stem and the buds are looking great with plenty of white tails and lots of crystals on the buds
It doesn't appear the spoty leaves are causeing any other problems.


I'm using CFL lighting for now as this is my first grow the lights are approximately 18 inches away from the plants

I was thinking of sniping the affected leaves from the plants but not sure if I should or not?

If anyone has any ideas please let me know.

Thanks,
Beau
