Help..Airy buds

i need some help my plants got 3weeks left and some of the plants arent tight and are airy.. i dont no what is it>>>>

Yea i think maybe it could be old seeds or strain of marijuana but dont take my word for it, I would actually like to know the answer to this question if someone knows about this as i have same problem with another one of my plant, also i have another plant that the buds are TIGHT i meen TIGHT and thats why i thought it could be type or strain of marijuana.

some insight would be appreciated

genetics dictates whether the flowers are gonna be dense or fluffy, can't really control it. Some people say molasses will help but odds are is, you got what you got.

What light are you using. Typically more light = denser bud, although, as Pureblood states, genetics still come into play (like with cloudy or amber trichs)

IT normal or do wax hair remover hahahah !!!

^Agreed. Genetics dictate what the plant is capable of acheiving, and then it's your job to bring it as close to it's max potential, as possible. Light intensity, is usually the most important limiting factor, after genetics. Then, it's environment, feeding, etc.....right on down the line, including everything that effects a plants growth/health.

^also agreed.....in my experience airy buds are usually the ones furthest from the light source.

question # 1: are you using bagseed? if so, get yourself some good seeds and then comeback to the garden.

thanks guys...

High temps are a big reason IME.
