Old leaves ok to Pluck?

Im flowering two plants right now. On one plant, the fan leaves are very slowly turning brown and falling off. They are soooo easy to pluck off too. I really dont use any force, I just pull them a but and they come off. Is it better to remove these fan leaves while flowering than to keep them on?

On the other plant, some of the single petal leaves on top, well actually they have covered the whole plant now, are blocking the buds. Is it koool to trim this baby up or will she not like the stress, stop budding and try to recover?

it is ok to remove fan leaf that is blocking the bud acces to light,but make sure you leave the ones that dont.and yes you could remove dead and dieing leaf.three weeks in i toook off all the bottom of the plant that was not going to ripen into bud,i dont think it stalled growth because the plants still finished in time.and were healthy.

yeah pull off the bottom dead leaves give it a couple days to recouperate. when flowering the plant focuses on feeding the bud growth and leaves and stems halt growing and die from the bottom-up naturally. it's okay to aid that pluck. i do

Take em off, improves airflow,only yellow ones tho

I always take off the few dying yellowish leaves at the bottom of the plant BUT I also take off a few near the top as they block the sun from my thickening buds. I just make sure not to take off too many of them.
To be quite honest, I am not sure whether this harms the plant or not BUT mine are as healthy as ever so I don't think so.
