Why lower buds better than top buds?

is there a fan pointing at them? if they are bigger, they shouldn't dry faster... also larger buds can be tricky.. they can feel dry but not fully dry. if they get sealed up, the moisture will even out and it'll feel soft on the outside again, so watch out for that, as that means they weren't actually dry, yet. maybe too much light fried them? -- evaporated off large portion of terpenes off the top, nearest buds? 7-8 days should be okay. That won't cause catastrophe. A whole plant drying in 7-8 dies is kinda fast, though. avoid light and heat while drying, that will help. If using a fan, never have it directly pointed at the plant... don't use a small enclosed space like a tent.. that is difficult to 'circulate' without a strong breeze over-drying the plant material as it creates a vortex in a tiny enclosed area vs a small room. larger buds don't naturally dry faster, so you'll have to simply look over the process for a cause to that effect. should be obvious...
