nitrogen in late flowering

hello all, i have a few plants all different strains, the one in question is a grape fruit krush, was one of the emerald triangle freebies from attitude a few months ago, well the plant is 2/3 weeks from harvest at the very most and it has a nitrogen deficiency, i was just wondering if i should leave it or maybe add one more dose of the veg ferts, i am growing organic so it wont be no high strength chemical ferts i will be adding, it hads been showing these signs for about a week, its seven weeks into 12/12

thanks

I would. It'll give your leaves a lil boost to help them feed the flowers.

yeah me too ,as long as the plant still gets PK then it'll be fine.

cool, i will add a dose in the next watering, so whats your views on flushing? with organic and chemical ferts? i have all the bio bizz line apart from the root juice, some say on the bottle stop two weeks before harvest others say use for the whole cycle, bio bloom and top maxx are the ones they say to use the whole way, what you think?

i would juss let her be and juss use regular water ur last 2 weeeks so ur bud dont taste harsh. maybe lightly brush(BBQ brush works fine or paint brush) the bottom of the larger fan leaves with a 25percent nitrogen solution for fast delivery or nute
