Hey mate,
Smelling a scent is mostly dependent on your recipients in your nose... some people just smell less then others... but, as said before, most flowers smell what they smell when they grow, but the actual smell needs to develop in curing... so at least 10-14 days of drying and 14 days of curing (more is even better)... so aproximately 1 month after harvest you will be able to judge smell... but be aware if you dry or cure in light it will have less smell at the end (and potency), the same goes if you dont have the humidity somewhere from 58%-62% during drying and curing to get the max terpins in tact. But even if you do it with the light and humidity 40%-50% you should get some nice scent at the end, but not max scent. And also dont expect it to be cherry vs lemon smell, it is more like cocacola cherry vs cocacola lemon - at the end it is still cocacola:) good luck with your grow 👊💪👌
