Pics help. Yellowing is usually the result of lower Nitrogen in bloom foods. I run a balanced ratio of NPK through harvest and no longer have yellowed leaves in flowering.

Sometimes it's ph lock out in your soil. Last, if it's lower fan leaves it's usually because the plant no longer needs the lower fans.

Maybe the canopy is thick on top and light penetration is weak at the bottom.

Adding more light or adjusting the positioning will help if that's the cause.

Looks to be isolated at the bottom of the plant. Move some lights down there or don't worry about it and let the plant drop the leaves. It will make new ones up higher on the plant where the light is strongest. This plant has a lot of stretch and spacing between the nodes. That's a sign that it's not getting enough light.

She will produce, but maybe think about adding another couple bulbs on the sides and top to get the plant to produce more bud for your time investment. Good luck man.

let them yellow its natural or you could of up'd the nitrogen earlier. yellowing on fan leaves is nothing to worry about if your a few weeks till harvest. some keep it green some like to let them yellow up some just dont care ;P
