Whats wrong with my plant?! (pics)

So my White widow X Big bud plant has looked awesome all season but now in flowering some kind of definiciency or other problem has begun to appear. The problem affects some branches worse than others, and some branches not at all. The worst affected branches have shown a draining of the healthy darker green leaf colour and appear lighter in tone, they have wilted and the leaves are curling down, and the flowering is slowed down alot compared to the healthy branches. At first I only noticed it on the currently worst affected branches but it appears that the draining of colour is starting to affect more branches and I'm afraid for my baby!! It is one of my largest plants and I don't want this to hurt my yield as we come closer to harvest. I want to do whatever possible to try and correct the problem before much more damage is done. If anyone has any idea what the issue may be or knows of how to correct the problem please let me know! It'd be much appreciated

I would suggest to get close ups of branches to identify the problem areas

Well the first 3 pics are close-ups of the worst looking areas.

lokkin like nitrogen because the whole thing is pale but wait for some more opinions good luck man

how long into flower, what are you feeding them ...info? I would assue the same as was already said n deficient. Have you run this strain before?

I would say its some kind of pH issue in the soil . If its not that, perhaps just that plant needs more N-P-K.
Are they in pots?
What have you been feeding them? and when?
Its hard to tell how far back those burnt tips go, might be recent. its hard to tell without more info.

Yea Jeff im beginning to suspect nitrogen, although it seems weird that I'd have a nitro deficiency now of all times. Anyone else think it could be nitrogen?

4ish weeks into flower. Planted directly in the ground. Soil was never amended. Have been feeding Molasses with most waterings except when I feed 15-30-15 blossom booster around once a week.

when you feed, do you adjust your Ph?
If not, theres your problem...most nutrients lower Ph drastically.
Ganja likes a ph of 6.3-6.8 in order to absorb all necessary nutrients.

Also, the yellow leaves point to low N...which could be because you only feed once a week...try every 4 days.
but that wont matter if you dont adjust your Ph...

but yes, even in flower ganja needs N..just not as much as in Veg.


side note: Careful with that molasses...a little goes a long way. I've ended up only using a few drops per gallon.

and ironically enough...I'm actually toking some of this very strain

Looks like N def to me also. But dont go dumping a bunch of nutes in just yet. This was mentioned before. It couls be your p.h. Causing micro nute.lockout. I wish you had a close up of one leaf. Are the veins yellow, or is it interveinal. If your bloom mix has low nitrogen, maybe add a little veg to your next brew. But go easy. This defeciency could be due to lockout and adding more just makes it worse.

No I don't adjust the pH but I've been feeding all along without adjusting the pH and only now has this problem come up, and only on this one plant. I think I may give this plant a few feedings of 20-20-20 veg fertilizer and see if that helps. Regarding the molasses I've heard that 1 tablespoon/gallon is the standard mixing rate and is what I've been mixing it at. Haha what a coincidence! Is it decent smoke?

It started from the bottom of the plant's.
The surrounding soil of outdoor plant's usually isn't abundant with nutrients so make a nice thin liquid fertilizer with N & pour around the base of the stalk.
Should fix it. Hopefully, only symptoms it's showing.. & it's in flowering so it's the most common.

I can take more pics tomorrow but the sun has set for now. Another piece of info: certain random leaves on the plant turn yellow and die because the plant uses the nitrogen in these leaves for the flowering process. When I pull on these leaves they come/tear off of the branch very easily. But on the weird deficient branches there are yellow leaves which i try to pull off in the same manner but they do not want to come off. They're still firmly attached to the branch although yellowed. This suggests N deficiency to me

AGREED!
If they pull off easy, it's wilting. So pretty much N 'cause the plant know's food is abundant & is trying to spare energy.

He said his bllom nutes were 15-30-15 which seems really high o the N to me...But if your soil is unamended I don't know. I amend my soil with all kinds of good shit and my veg nutes are 4-1-1 and flower is 3-20-20. Sounds like ph or nute lock-outissue. The yellowing leaves mid-way down the plant is pretty normal for the time of year..Mine has a bunch, whne they get really nasty looking I pick them off.

I grew in natural soil this year with zero ferts. Looking at 2lbs on some of them.

whatever you do do it slow. So feed one plant some N and see what happens. If it likes it feed the rest. Ph and lockout? Not real sure being in the ground.

How often are you watering them? And your average temps? 15-30-15 what mixed me up. Not really sure how to help you.

If it is a pH issue then simply pH'ing the water to around 6.5 before watering should correct the issue correct?

The 15-30-15 bloom nute is just some no name stuff that my local store sells (the name on the label being the name of the hydro store). They recommended using it so i bought it but have only fed the plants with it 3 or 4 times.

I water everyday if possible and the temps havent gotten too low outside yet. Lows of 9 at lowest but mid teens on average. I will try pH adjusting my water and slowly feeding the plant in question some 20-20-20, hopefully things will begin to look better.
