More N or weed control

With apologies to those struggling to get their first N on
My wheat got 50gk N+S03 3 weeks ago next Tuesday.
Walking round with the agronomist yesterday and we would like to get some BWS on to tackle some particularly nasty brome. The dilemna being, do I top the N up first or herbicide.
My gut feeling is to go with more liquid, but another small dose and have 4 passes ( I don't have a lot to do, so logistically won't be a problem and would actually help as we can go with lighter loads on still wet fields)
Just wondering what the wisdom of TFT would suggest? @Brisel and the usual suspects please

I'm flattered for the tag @Renaultman! Not sure what I can do from down south!

Do you know what your soil temperatures are at around 4" deep? What has been the average air temperature? Broadway Star/Palio needs active growth to work. A couple of degrees higher than Atlantis/Pacifica type products too. If it is anything like Oxfordshire recently, I'd say it was still too cold to get a good kill. Very frustrating when you can see the brome tillering - how big is the brome? Which brome species? What other weeds are present? What is the crop, what is its condition and what is the growth stage?

From what you've described so far, the next N could wait. Why do you want to put more N on now? What you've applied so far ought to see it through to GS30.

More importantly, which did did your agronomist say to do first? You've paid for their advice!

Thanks for coming back to me.
He says BWS but looking at the weather and historical issues with going too early with BWS, but that's Ryegrass, another story.
My thoughts for more is I only went with 50kg/N soil indices will almost certainly be depleted and I'm thinking maybe another 64kg N, if the weather doesn't look ok for BWS in the following week, got a fair mixture of brome issues (you did warn me) biggest issue being sterile brome, it's by no means catastrophic but I want to keep a lid on it, before it is
Wheat is all sorts of growth stages, from well advanced, to just nicely getting going.

This isn't the year for pretty crops , grow it cheap then burn it off

Imagine putting more N on and then conditions mean the crops/weeds romp away and can't get on to spray for 2 weeks, then imagine the other way round. Extreme scenario but Which way would be less desirable, thats how I decided
It's been bloody freezing today, too wet to get on with anything, I still haven't decided which way to go BWS really doesn't like it cold, I can see me just spraying the bad bits off.
