Those buds don't look ''airy'' per say. It looks like you have enough intensity to create dense buds (tops at-least) but not enough for big dense buds. But also some strains won't get fat colas and can look much like the ones you have, only a lot more tops if trained better. Topping will create more colas in better light distance and in turn they will be slightly bigger on avg.
The walls also don't look very reflective and could also be a factor.
Just noticed the W you use. 300 would be some what ok if you trained the plant properly. A 315 would be better but not by miles at current, the biggest improvement will be from training and making sure the walls are not wasting light.
