Hello! If you feed the plant properly and the environment is good, it’s all about genetics, some have airy buds other are more compact!
You can try some stuff to increase tricomes and the buds be more fat!
• Try to had molasses on your feed( absolutely result for me, love molasses!) 1-2 tablespoon per gallon.
• have a good bloom nutrient
• you can drop the temperatures till 16 Celsius in late flower to get more fades and appear other colours to your plant, I believe that the buds become more fat too!
• leave the plant at leat 48hr in a dark room before chop
• good lights!
• always have a good airflow
•reduce the humour to 45-50% in last 3-2 weeks before chop
• have a good slow dry and a good cure!
Wish it helps mate!
Drop a like in my diarie if you like !
