Oh, wow, Misti! This is a real bummer. So sorry.
I also think it is too late to save the plant. But the buds look well along.
Harvest them now and dry/cure to see if they still make a good smoke. Or, try making dry ice hash or RSO from the buds. They should still have salvageable THC.
Don't forget to try to figure out what went wrong. Too dry? Too wet? Too hot? Etc. . .
