Jesus... what you all write here for bullshit is amazing... and painful
The yellowing you are seeing is a totally natural occurrence during mid to late stages of flowering. Most all of us cut out nitrogen at the begging of budding, as to reduce the leaf to bud ratio, as well as to improve the overall smoke and taste. Do not cut leaves, Do not up your dose of Nitrogen, keep using your bloom ferts until 2 weeks before harvest and switch to neutral ph'd water for the remainder to flush out whatever remaining nutrients are still lingering. You are overthinking this way too much. Your girls look just fine.
