Hello, it seems like they were often dry during the grow. Yellowing of the leaves at the end is okay if it starts from the bottom and not when the upper fan leaves look dried out and burned. From week six, there's not much you can do except start flushing. You can still fertilize for a few days, but it won't really help you in the end. Now the time begins when the buds are maturing. (The mass and volume probably won't change drastically for you anymore.) It's very important to stick to watering intervals and be flexible with the nutrients, not necessarily following a strict schedule but adjusting to the plants. And with every change, no matter how trivial it may seem, react and counteract immediately if possible. I still wish you good luck! And setbacks and mistakes make a grower better.

I’d still feed. You’re not even really mid bulk yet. But i think flushing for 2 weeks before harvest is unnecessary and counterproductive. Id pull off fully necrotic leaves. They’re doing nothing at this point. Also those are not yellowing from natural fade or senescence. I’d go the full 8 weeks and assess from there

Depending how you like your bud. More of a cerebral high, harvest when there's 70% cloudy and has that % goes up and trichs go amber you harvest at your discretion. I aim for 90ish to 30-40%Amber's. Maybe a little more on the amber side by the time everything has almost couded up. But, again that's up to you. 36-48 dark rest when u are ready. Hang dry whole - the dead leafs. In 18c (that's max temp you should reach) my drying room is 17c most days and between 55-60 RH the latter to be the one to aim for. Good luck
