Early Flower question

Thread starter #1
I lost 2 out of 4 of my beautiful NL girls because of a stupid first grow mistake with ph problems and trying to fix too much too fast with baking soda. Dumb is know now. The question is: all four were 5 weeks into flower;and had really nice buds all over when they took a header- including 4 nice COLA buds. Can I still harvest them and dry/cure like they were complete? They were really sticky. I know they weren't fully mature- but they have to have some value at this late stage.

Thanks for any help.
