Can I wait two more weeks until harvest, or do I get diminishing returns?

if you hang an entire plant to dry, you have 10-14 days before you need to do anything. If it is a matter of a day or two, i'd say do what is convenient because wahtever is potentially lost is going to be insignificat. two weeks is a long time, lol. buds are ripe. it's a matter of scoping trichomes and none of these pictures show that sort of detail. if it isn't ready now, it's ready within days. flush or don't flush, it won't change the composition of the buds, so no worriees there... do what makes your ego feel good on that like most others do, lol. What you do the last few days won't make a huge difference, but over-ripening ruins flavor and reduces potency.. it's a bad idea all around. Might look prettier with more exotic colors, lol.
