[divestoned]

I hate to tell ya cuz...but you can probably add potassium to that list...a nitrogen deficency itself would create a more evenly yellow leaf before it got to that point. PLus...I swear I see a ??? Wait! Well...Let me ask you this...just for fun. OK? Do you use epsom salts? check ya later

[divestoned]

no no epsom salt but i hear it works good as a ph up......

[bud luv]

yeah that's not just an N def

[stinkyattic]

you have FAR bigger problems than N def... in fact judging by that nasty BURN it's not a def at all but a lcokout situation

[latewood]

It looks like a possible N with a Magnesium overdose...but actually I think the inner part of the leave is too green for Nitrogen def...Read up on Mag and Zinc toxidity, because when one element% is too high; Another is being locked out...Magnesium oftens conflicts with calcium...(good reason to use calmag+...perfect blend) goodluck...

I woulld lower my EC and by adding a fresh batch of light nutes...dilute your recipe by 25-50%
