Trimming leaves in flower in bushy/dense plants

[Yodan69]

Hey fellow growers,

This is my first grow and I've faced a couple of unexpected challenges. For once my plant didn't start flowering automatically so I switched the light cycle in week 6/7.
Therefore it got much bigger and bushier than expected. A little too big for my small closet. It is a 2x2 ft closet. I'm thinking about either getting rid of the bottom third of the plant or most of the fan leaves because there is almost no light at the bottom.
What are your thoughts and suggestions on this plant? Do you think it's looking good in general?

Sorry for double posting. I'm really new at this. Here are the pictures.
Btw I already trimmed the bottom fifth and the flower is in week 9 now.

Thin out at day 21 of flower then again at day 45

at day 21 you will see where buds will not develop due to lack of light remove everything that is not developing

Wow, thanks for the quick reply!
So basically, I'll remove all the bottom buds and branches which look tiny?
Thinning out means to cut off some fan leaves, right?
Sorry for all these beginner questions.
