Help! Yellowing leaves in flowering! Pics!

Okay so overnight the bottom fans leaves started turning yellow on one of my plants, im 2 months into flowering what could this be?

first two pics are of the plant of the yellowing leafs.

third pic is top cola of a plant and the leafs look orange?

Thanks everyone~

plants naturally start turning yellow towards the end of flowerin
its because they start usin up all the N they have stored up
your plant looks real good, what strain
