Wired Def

[CannabisGuy]

did anyone recognize this Def ?
i rehoused her from under 250W to 400W with cooltube , to a 180X80X80 tent , with extractor fan 125cc.

it's start to appear on some of the upper leaves, the closest leaves to the buds , and every day it's spreads ..its striks from bud to bud ...
it's looks even worse than those pics..so take that into consideration.


Mag dowsnt behave this way , cause it's comming out on the upper younger newer leaves.
Zinc ? Sulfur ? or even salt build-up ?



and now it gettin worse ,
the paling increased on the "effected" leaves , they were really dark green and now they light green and starting yellowing from the tips into the leaf ..
and it's not with any order , from downward to upward or such , it's scattered in all different places on the plant

all the leaves that under the canopy are bright green but i think that's is just lack of light penetration.

also the clones are also behaving wired ,not in the same pattern but pale green scattering , some yellow as wellon all kinds of levels in the plant.
remember it's looks even worse than those pics.

thanks in advance

I have a similar problem going on with my leafs, havnt been able to find out what it is ether. Im in hydro so I changed out the res and it seem to slow down the dieing leafs but I still have the patchy leafs all over the plant, really don't know what to make of it and it seems to be a bit of a mystery to others aswell, if you find out what it is let me know

I not a dirt expert, but at that stage of flowering you are probably using low nitrogen ferts and that can cause yellowing (N=Green). I'm going to say if your really concerned about it look more carefully at what you fertilizers has in it for nitrogen and make adjustment accordingly. DON"T over feed and burn your plants at this point your sooo close. If it was me, I would just keep thing the way they, that little bit of yellow is not a problem, thing will be fine. For peace of mind go look at some other peoples grow journals and see what there plants look like at the later stages of flowering and you will notice this yellowing is very common. Good luck!!!

thanks man,

but yellowing from N def is climbing from the bottom up..and this is on the top and all kinds of levels in the plant.
and im not that late in flower stage , im only on week 4 , and got at least another month to go.

it seems to be innocent and harmless on one hand , but what's going on back stage ? , im better safe than sorry.

Your plant will start pulling nutrients as it matures from the older leaves to supplement the flower development, causing yellowing. I'm not saying you wrong to want to fix it, I'm just saying please don't pull the alarm and add a bunch of voodoo snake oil and burn those plants they look pretty darn good. You look like you know what your doing just don't forget to error on the side of caution with ferts at that stage of the game.

yes .
but she's not pullin from the older leaves ,it's on the younger newer leaves.
i wish it was an N def , it's much easier to treat.
