They are def close, better pics of bud/calyxs would be very helpful in knowing if they are ready to come down now, very hard to determine that by fan leaves. The yellowing/fade looks more genetic than it does them sucking themselves dry of N.
Give em at least a wk. That last one looks 2 wks out. Don't worry about the yellowing. That is how u want them. I get mine as yellow as possible before harvest. The least green when harvested, the smoother the smoke.
