Some buds just don't chunk up tight, some do
It's no problem, doesn't affect potency or quality
Generally, stronger lights (CMH/MH/HPS) tend to produce tighter buds
Some folk roll them when they are dry but sticky which can help the final bit of dry/cure
Looks pretty good to me
Don Carlos strain 7 week of flower, Almost!! Then Hell's Fire 5th week. Also, i have some wedding cake clones I brought back from the dead from a friend. Amazing how much stronger seeded plants are as the clones are the same flowering stage, but thats normal Im sure.
