Looks like she still needs a bit more time, there's about 5-10% amber trichomes and 90-95% brown pistils.
I'm not adding any more nutes and gradually decreased light cycle to 14/10.
Nice looking flowers brother...I would check your PH meter, I calibrate mine at minimum at the beginning and end of each grow, but they have a tendency to get out of whack every couple months, especially if you forget to cap it for a few hours. Good luck brother!
@Canna96,thx, but I think it's fine, I always check it periodically, or when the reading seem off, but it always turns out its fine. I also add few drops of KCl solution to cap, it conserves the electrode.
