It looks like your fan leaves are just Nitrogen Deficient which is perfectly normal for your 5th week into flowering. Remember, your plants are pumping all of the nutrients they can into the bud in hopes of making seeds to perpetuate its existence. All looks well.
If you were vegging on the other hand, you'd have issues.
