N definciancy help!!

ok so i just figured out i have a Nitrogen def. i think i had this before i started flowering but now i am flowering for about 19 days. i came to this conclusion because my plant has been droopy and barely growing for quiet some time, and then the bottom fan leaves turned yellow and seems to working its way up. So my question is, should i try to fix this now or not?
I believe during flowering you need less Nitrogen i think. currently im using FF open sesame for nutes and will be using molassas.

thnx for all help! toke it up

Less than during veg, but that doesn't mean none. You should have addressed the problem a while ago. You can still do something, as long as it's not dead, right? If you're already feeding, either increase frequency or GRADUALLY increase strength. Make sense?

yes, is there some thing i can use to just add some N or just continue using the FF watcha think?

I don't have that FF fert, what's the NPK on it?

ok thnx alot!
