Hello VanBrando, i think there are alot of thing you could have done different but thats the past.
Lets talk about the future.
How i see it you cant do alot to bounce them back up at this stage, so my only advice is to flush them a few days until all the leaves almost are dead or yellow and brown.
After that you just cut them, dry them and cure them and hope for the best of it.
I do also wanne give you some extra tips on your next grow.
Maybe you can train your plants next time a little bit more and train them till the end of harvest.
I would open them up much more so theres more light penetrating more buds and also better airflow throug your canapy.
I'd also recommend that you defoliate and remove the lower growth that cant or almost has light to improve the buds that are under the light.
Hope it was an helpfull answer, i wish u much luck brother.
Keep on growing, Peace 😎
