You can try flushing if you want but if its too complicated just dont worry about it. It takes a while to start to call the harvest yourself and then you start flushing. When all the hairs are orange, if youre into checking trichs and they appear ready, now you flush. New people tend to start flushing weeks too early like this case.
I wouldnt worry about harsh smoke, Ive grown several strains, not many because I run clones over and over.. I found that some strains are just harsh no matter what you do to it. While some can be dried brittle no cure and smoke smooth enough.
The ones that cure will only need 2 wks to make that happen and its crazy what can happen if its meant to cure. Smells change and intensify, smoother smoke. Some strains wont do anything when curing but of course will help it smoke better if it wasnt but its still crappy.
My main pheno is like that, Ive tried to cure it several times it just doesnt do much. I use it for 100% dabs tho. Ive gave it away to smoke and people say its fine, good stuff.
