That's a big plant pal.
Don't get hung up on size of your buds. Look at the f..kin length of them colas.
THERE HUGE. That's where the energy has gone my friend.
You will find you'll get shorter autos and, yes, you'll get denser buds. But, for its length. The size. The quanity is more than normal pal.
50g is good to get off an auto.
You maybe have 3-4x that. 150 easy.
Good luck
