Flowering, but leaves are yellow and dying - Please help

Yup! It's the Nitrogen! You started feeding them with a high N and all of a sudden you went to a bloom,like High in P,correct? If that is the case,you need to flush them as soon as possible!!!!!Get them to a certain pH,the soil.Then when they get outta shock,took a while for mine to come around! They did,though!Gonna get pics up tonight. I did the same thing with mine! Jack Herer! Knowm,hooked me up with a solution!It was my soil mixture! No perilite.So all the salts and unused nutes stored up in the soil and thus overnutation occured!Yeah! It's a word!LOL..... Looks like to me,ya need to just flush'em and as close to harvest as you seem to be! No need to fertilize anymore! Just get'm stable as to have a potent crop.Alotta folk's flush a week or so before crop!Say's it get's rid of all the nute taste in the bud! Seems so to me! Just indoors,though! How ya gonna flush a plant in the ground,that's over nutted? Go Organic!

mate ur plants are fine and at 4 weeks into flowering i wouldn't be giving them any N . N is only used for veg growth and doesn't make any more bud . ur plants are taking the N from the leaves , this is totally normal all plants do this as the get to the end of their life cycle . TAKE IT FROM ME UR PLANTS DON@T NEED N . if u start feeding N now u'll leave ur bud harsh to smoke . continue with ur flowering feed for another 2 weeks them flush them and give them just ph adjusted water for the last 14 days.

stop giving Nitrogen 2 weeks prior to harvest for a better taste, if you want to flower longer then give it some now!

First off, thank you to everyone for your insight and suggestions.......

Here's an update:

I flushed the plants, but it might have been too late. It has now been exactly 5 weeks of flowering. A lot of brown hairs are appearing - seems like 30-50% on some buds. Did the nute burn / N deficiency reach the hairs? Or is it just time to harvest?

What do I do now? Should I harvest immediately or wait a few days and see how they respond to the flush? Continue with flower nutes in a few days?

Thank you in advance!

Anybody got any words of wisdom?

You are really in to deep to make any serious changes or dramatic POSITIVE effects to your plants..

that being said,, it is always possible to FUCK a plant up... even up to the last day...so becarful and just ride this one out.. make notes regarding your grow and try ot improve on it.. You are still going to have a decent harvest..

: )
cheers

Mine are 3 weeks away from harvest at least and at least one of my plants has alot of red hairs but it's nothing to worry about, mainly concentrate on the hairs on the main cola.

Those plants are not fine bro. lol

If it isn't a nute burn problem it is a PH problem.
What is your PH?
If your ph is right.
It has to be the N OD.
It will be OK>
Just flush with plain water for the rest of the grow.
Or for a couple weeks at least.
But after that is the flush anyway.
It might take a little longer for them to finish.
But they will recover.
The hairs are fryed for the same reason yes.
But not a problem.
Those hairs are for catching polline only.:thumbsup:

Jdog - I don't have equipment to test PH. Is it worth it to buy it now? I flushed each 2.2 gallon pot with 6 gallons of water yesterday so the PH should be somewhat normal... What do you think? I was thinking use flower nutes once a week (I have Canna Terra Flores) and then in one or two weeks flush again and just use water for the last two weeks (putting flowering time at 8-9 weeks). Sound like a plan?

[Jdog7000]

OK,that is your problem.
You have Nutrient lock out do to your PH being off.
The tap water is not the right PH for MJ.
You need some PH down and a PH tester.
It will help your plants in a huge way.
It is one of the most important things about growing weed.
So go get that stuff and your plants will heal and finish.
It just might take a week or 2 longer to finish up.
Get a magnifing glass to harvest the chrystals at the right time.
Beacuse your hairs aren't going o be acurrate now.
