Clipping during floweing?

some of the fan leaves on the bottom have purple stems and are lookin' like there gonna die sometime... I'm 4 weeks into flowering will it fuck up the growth if i trim the leaves, there also bloking light from newer growth underneath.

what should i do?
any info will help.. thnx

Ok.. All the trimming is gonna do is just slow down the growth for a few days(2-4) but not stun it . Nothing bad will happen.

if theyre gonna die hack em

Yeah, I just trimmed a couple fan leaves.. Do it, it will get more light to the needed areas

i've been triming mine with no bad side effects
