    Default Nitrogen Deficiency too early in flowering?

    All of these plants are 45 days (~6.5 weeks) into 12/12. The first 2 pics are White Widow, the last one is my Afgoo. I'm concerned that the Afgoo is so heavily yellowed, as the flowering time is listed as "60-70 days", especially since the White Widow takes "60 days" and is less yellowed. Does this mean that the Afgoo is closer to finishing than the WW, or do I need to add Nitrogen?

    I vaguely recall hearing somewhere that all of a plant's leaves should be allowed to yellow. Does it matter if they are all yellow? Does this affect the final product at all?

    First grow, so thanks for being patient.

    "Healthy fans make for healthy buds"

    IMO the yellowing fans @ 45 days is not telling you it's near completion. It's telling you she's hungry. Most bloom nutes do not have sufficient N, therefore it is presumed to be normal that leaves die. The lower, larger, older leaves may die due to lack of light, but the cola fans should remain healthy throughout flower IMO. The trichs are a better indication of flower completion.

    Your girls are beautiful BTW

    Thanks for the advice and compliment!

    She just went into her dark cycle. If I feed her in the "morning", 12 hours from now, should that be enough to correct the deficiency without too many problems? Or should I foliar feed?

    Are you going to feed her high N grow nutes in the morning or just adding N? I would start by giving them just grow nutes tomorrow to give them a nice dose of N. The next watering I'd give them half grow and half bloom so they still get lots of P and evaluate from there. Your dead/dying leaves will not get greener but the problem should come to a halt with no new leaves succumbing to yellowing, hopefully . Do some experimenting. This method has helped me in the past, but each individual plant is different.

    Good Luck

    I like to really blast my plants with N during veg, and a couple of weeks into flowering. After that, i use high P nutes, but ill throw in some high N every now and again.

    Most of my leaves are severely yellowed. There's no way to help these recover? Foliar feed maybe?

    And if not, should I plan to harvest this girl early, or will it just affect yield?

    Also, if I give this plant veg nutes, can the plant get the Nitrogen directly to the buds through the roots, even though the leaves are yellow?

    You want to be feeding her N all the way through veg and even a couple of weeks into flower, this promotes healthy growth, but when your plant reaches optimum size in flowering look more towards high P+K ferts.
    Now that you have so many yellow leaves all you can really do is chuck in some N and see what it does, im thinking its a bit late for that tho.
