Hi!
Keep the humidity in the jars above 55%, best 58 to 62%.
If it sinks below 55%, you destroyed the terpenes. So all the taste is gone.
Some flavors like banana for example tend to develop after 2 months of curing. For me, when the weed is nearly finished, the last bud in the jar will smell like a ripe banana. :)
So try to keep this rest humidity that is necessary in the jars and you will be fine after a while.
Keep on growing!
