I don't think I would do anything to try to correct the yellowing at this point. Adding extra N now could prolong flowering. In my experience, once that late yellowing starts in dirt, it's pretty damn hard to reverse it.

Something to consider next time is adding a spray the first couple weeks of flowering. Although I don't think it's an organic product spray and grow works real well. And lately I've been using LC 10 + 7. Both have the minor minerals that can start deficiencies in flower. The LC has 10% humic acid in it as well.

And if it's any consolation, some of my harvests that had early and prolonged yellowing were very strong and flavorful medicine.......good luck......shredder

You are suffering from a lock-out condition. The first thing to do is flush. Don't add more nutes as they won't absorb anything until you correct the lock out. What is your ph when you feed/water? What is your ph at runoff. If you haven't checked your runoff ph you might be surprised at how off it is. Just guessing from the looks of your plants your ph is under 6. Nitrogen is absorbed best at 6.6 to 6.8. Fix this and resume your feeding schedule. Are you doing anything to keep the roots healthy? Look into Great White, Quantum and phcbiopak. I also use cal/mag, Epsom salt and molasses. Those leaves should not be turning yellow until the very end. Also, if your ph has dropped you can control this by using dolomite lime.
