you could take a few off the top. try to leave at least a leaf or 2 on each, but get light to hit deeper on the plant to promote a larger zone of quality nugs -- in the center more so than the outside of canopy. if you take too much off, you hinder yield.
as far as pruning anything.. i think all you have is strong colas... but, if you have one that's only a node or two and stashed under foliage... i'd still keep it if you do other stuff like edibles and bubble hash. the plant isn't unruly or too large to provide, as long as it isn't a significant portion of the total. but, that's the top of crap you lop off near bottom.
i taek off lower leaves, not for the benefit of the plant, but because i want easier access to water, lol. However, i'm farily confident about not running into problems later. leaves are armor against stupidity, so have a really good reason to remove any. they do exist.
don't worry, 1 week into bloom gives you leeway... should be plenty of time to grow back a bit.
