Usually airy buds is an indication of inadequate light. Also sometimes if your area is extremely heat stressed then your buds dont form in a compact way.
Too hot in your environment, you have enough light for sure. Gotta bring those temps down.
Look at it this way, the lower your temps, the closer you can get your lights to the canopy, which equals tighter denser buds ( that's just a nutshell comment BTW ).
