Last weeks and weak buds

It is tooooo late, there is nothing you can do at this stage to alter the outcome. 4-6 weeks ago, yes, but now, impossible.

Looks like it had a n-deficiency a few weeks ago... add more N, maybe it's not too late. Yellow can recover, necrotic spots do not heal. REact sooner next time. If the canopy heals a bit, it's still photosynthesizing and it can still power the ripening. It's a bunch of bro science nonsense that a flowering plant needs little to no N .. it still needs plenty as proven by your canopy showing major n-deficiency all over. it is invovled with a lot more inside the plant than just chlorophyll produciton or leaves/stem elongaction (a.k.a. "vegetative growth") How fast this progressed to get to this point is aguide to how big of a reaction you should have as far as adding more N. can probably overdo it a bit for a couple fertigations but better dial it in better before long or you'll have the opposite problem in short order. Also, don't defoliate so much. Removing leaves just exacerbates a poorly formulated fertilzer balance. All that barren space.. all that wasted light not even hitting a plant... also less than optimal.

Hello mate, i'm sorry to say that by now you can do nothing to have back something more than you already have so or you do like Ultraviolet ( reveg your plants) or you become at peace with your result. Good luck and happy harvest if you'll do it!

Could snip everything off you want to harvest, throw it back into veg for 4-6 weeks then re-flower if you wanted another bite of the cherry. I keep meaning to try myself to see if it's worth it or just how much is lost on a 2nd flower in terms of yield.

Well, all you can do is take heart, we live and learn, so long as you understand where you went wrong and you have an idea how to prevent the same thing happening again then its all gravy, onwards and upwards, if the time for fattening has past then its passed there is not much to do now. Just harvest and cure what you can. You still have high ratio of yellow pistils i see, 💛 I'd still give her another week or 2 until they are more orange. She may have missed fattening but doesn't mean she won't terp up on queue. Hopefully she still smokes 👍. Best of luck.
