Larger leaves yellowing!

My plant is about 5 weeks into flowering. The larger leaves are turning yellow. Is this cause for concern or is it normal? I've been giving it a 10-15-10 plant food once a week.

It's normal. the plant is using up the N makin' buds.

You may wanna ease up on the nutes as she finishes up...plain water for 7-10 days at the end of her life will help smoooth things out tastewise...etc. and will help her finish.

good luck
