Here is the Tent - Cherry on Top. She's getting really sticky & Frosty. But here I go again getting yellowing & dying off of upper leaves. @Emilya Green this is the most affected plant that I asked you about. I think she's within 2 weeks of finishing or there abouts.
ok, it makes sense to me now. If you look at your buds, the true "top" growth at this point, they look wonderful. They are getting all that they need and then some.
To get there though, your plant has been sacrificing leaves from all over the plant. It is consistent too, with no actual areas of the leaves that are going yellow, indicating certain elements, this is a full out cannibalizing of the leaves to full yellow, and then complete drainage and withered up leaf until it drops off of the plant. The plant is completely and methodically using up its resources all around the plant.
There are only 3 elements that are this mobile, the big 3, NP and K. P is stored in a specific place in the leaf, but N and K can be stored in every cell. When those are being pulled for use at the top, the entire leaf goes evenly down.
We know it cant be N.... so clearly this is a K deficiency, a major one. So far by the term some use to describe it, senescence, the plant is sacrificing parts of itself for the finishing of the buds. This does not have to be happening though, so now you have to decide which camp you are in...
Do you believe that to produce the best bud, the nutrients must all be used up within the plant?
or
Do you believe it best to feed right up to the end, giving the plant everything it needs, and then relying on the cure to sweeten the plant after harvest?
or
Do you believe in stressing the plant at the end to increase potency?
So there are several ways you can go with this, and depending on your style, any of them are correct... they all work. Which works better? That is up for grabs.
My personal preference is to feed right up to the end as organic grows have to do, mimicking mother nature, and allow the plant every chance to express the best its genetics can produce, rather than relying on tricks or brute force tactics to produce a desired end.
