Question about harvesting

I had an auto pineapple express that I did the same thing to all the leaves fell off even the sugar leaves. I left it in for another week with just the buds and it turned out fine as long as you were watering you should be OK, but just keep an eye on it because when it does start to finish, it’s gonna go fast

I don't think the problem on your plant is about the flush. Many says that flush is useless and there are scientific proof of that BUT leaving your plant without nutes in the last days should stress her to produce more rosin and is also a money save. I run hydro and I've flushed for even 2 weeks and I never saw results like that , so in my opinion your problem is different (e.g. too much pH fluctuations, overfeeding, deficencies...) . My advice here is to harvest now. Good Luck !

Don't flush bro it's a myth , why would you starve a plant when she needs it most. Big Flowers requires lots of food. Feed her till shes done, I usually stop feeding the last week simply because there still enough left in the soil but I don't do run off watering at this point just enough the wet the whole medium.

Because you stopped feeding to early is why she looks like that, I can't see those leaves working anymore so might be best to harvest now.

My advice? Get a magnifying glass or jewelers lope and learn to judge it off the trichomes. All other methods of judging ripening is dodgy at best. All your pics really tells us is your leaves are dying. If you let the buds get crispy its only gonna be good for extracts or edibles.
