do i need to prune

my plants r 7 wk old and the leaves on them are starting to go yellow i understand this is natural do i need to prune my plants at all some of the fan leaves are covering bud areas and im not sure if to cut them off

ya cut them off just waste of plants enery to try and keep them alive but post some pics just to make sure its not some other problem dying leaves can mean other things

i dont think 7 wks old is normal for yellowing maybe 7 weeks into flowering

Might be time for some nitrogen, food.
