Tip of stem is brown and not growing... should i snip it?

As the title says, I had a pH problem with my water and my plants been growning since then so please disregard the plant condition in the photo. EXCEPT the main stem. Its always been brown on the very tip since planting day and has refused to grow. How can i get it to grow? Cut it?
It has gotten fatter but not taller.. Any advice?

better off leaving it, its healed over, cutting will just open it up to possible problems

isn't this gonna kill my entire yield though... nothing will support that plant as it grows. there has to be something I can do to get her to grow.

maybe start over... If you cut just above the node it may branch, but the branch on it now is already the new main cola

i won't start over, I'm probably gonna add 1 more plant. but we will see how she takes. I think I'm gonna have my girl snip it.

The main stem is no longer the main stem and is finished growing, the new growing shoots will now compete for that honour. Also get temps below 80.

My girl keeps her a/c on all day in her apt. I don't believe they get that high. I will check though.

Yo buds. do u think it'll banch if i cut it? Im trying to get the biggest yield and every g helps...

Dont top it again yet ,for now just let it grow another 6 " or so then tie each growing branch(gently pull them apart) to the sides of the pot to let the inner growth come out. I just use pushpins in the side of the pot with tie wire attaching them. It does look to be growing well now.

I would top it again right underneath that new growth...but that's just me.....Doing what BUDS suggested will have the same effect but will be more work
