Flowering, but leaves are yellow and dying - Please help

[taylor324]

Hey, so here's my deal....

I have two plants. Both started as feminized seeds. One is White Widow, the other Easy Bud.

I vegged for about 7 weeks and now I have been flowering for about 4 and a half weeks.


Most of the lower leaves on both plants have died or fallen off. There are a lot of bud sites, but even some of the leaves by the flowers are yellowing, curling and dying.

Using 400 W HPS with relighting bulb (supposed to be similar to hortilux). Used 400 W MH for veg.

The only ferts I'm using are Canna Flores and I only use it once every 2 or 3 times I water.

What should I do? Is this normal? And how much longer should I flower?

Thanks!

Over nute maybe?

[iwantFUEGO]

wow thats a shame... id be freaking out.

[mscaboo]

your plants have a nitrogen def,at what time did you stop using veg nutes?

[OmegaVermelho]

I´m no expert but it looks like over nute burn....and how far is the hps from the top of the canopy????

[Garden Knowm]

Hang in there chief.. they are gonna get bigger.. i see ZERO brown hairs...

[taylor324]

i stopped using veg nutes when i stopped vegging. so that was 4 and a half weeks ago. at that point i switched to flower nutes.

hps is about 8-12 inches from main colas and 20 inches from other bud sites...

anybody got any suggestions? do plants look good otherwise?

[taylor324]

can anybody suggest anything? thanks in advance

[sjacobs713]

flush em, and then let them recover and start over w/ nutes....
read this article about flushing them in the bathtub, makes it a little easier..
forgot the link to the article, but basically it said:

fill your tub w/ water, and then set your pot in the tub and the water will soak to the top of the soil from the bottom ( let sit there for about 5 mins ),
pick the pot up and watch all the yellow liquid fall out..
repeat same process until water comes out clear... i had to repeat 3 times w/ 3 gallon pots..
FYI ..... i use those cheap , plastic pots, and they come pre-holed, but i have found that the water does not drain properly from just the 6 holes.. i drilled holes on the bottom of my pots, and drains alot better...

also the guy at the grow shop that i spoke w/, told me to not let the soil get too crunchy... ( i had read somewhere on these boards that it was good to do that so the roots can get oxygen , and i was doing that!) it's not goo to do that, when there is no water for the roots they start to pull moisture from leaf's...
just some thoughts!

i am working on my first grow , so i am far from any kind of expert...

GOOD LUCK

It looks like your plants need nitrogen.
If you stoppped giving them veg nutes they will use wht is stored in the leaves.
Either that or nutrient lockout do to a wrong ph.

[stinkyattic]

That's N deficiency for sure.

What you are seeing is excessive, but some yellowing of lower leaves that far into flowering is normal.

Like JDog said they are now processing stored nutrients. The lower fan leaves are the reserve and their nutrients are being consumed as the plant focuses on reproduction.

Be careful not to overdo it on the N during flowering.

[taylor324]

thanks, everyone. so i guess i will try a flush, but then after that should i keep using canna terra flores? or is there some other way to get the N levels back where they should be?

thanks!

[taylor324]

I'm trying some fish emulsion 5-1-1. Hopefully it'll work...

[OmegaVermelho]

Hey taylor keep us up to date on that with some more pics ok.....its a good thread

[highweedskunk]

yeah man don't worry just flush that what i did and i just fed lesser nutes turn out good in the end

[GrowerXLT]

I am having a similar problem and also have pictures. Here is my thread, if anybody can help out I would appreciate it.

[Jdog7000]

Maybe the light is too close?
Is it burning the leaves?

[Opie Yutts]

I don't think it's a light problem because mostly the top leaves would be the problem area, or at least the top should look worse. This looks like lower leaves too.

[justaseed]

what's the ph? looks like you have a ph prob to me. do you ad dolimite lime to the soil mix? an absolute must imo! the way the yellowing leaves have brown spots in them is one of the things that make me think it's ph issues. test the ph and post the results. without that info noone can make a definitive dx./rx. imo. keep us posted, i'm curious to see if my suspisions are correct.

[GaGrown]

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.

[GrowinGreen23]

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

[taylor324]

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!

[taylor324]

Anybody got any words of wisdom?

[Garden Knowm]

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

[KHAN]

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:

[taylor324]

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.

[taylor324]

Jdog, thanks a ton for all of your help. Any suggestions for PH equipment that's easy on the budget?

[justaseed]

you can get a ph test kit for abot 5 bucks at any pet store! don't harvest your ww's at 5 weeks. i always let mine go at least 10 sometimes even 11-12. ww gets better the longer you flower for(within reason) i am pretty sure it is ph prob. as well. i don't uderstand how people can get through a whole grow without testing ph. i tested ph of the water/ferts every time i gave anything to my plants. most fertilizers are way to acidic and after mixing up the fert solution the ph must be raised back up to around 6.4 with ph up before it is givin to the plants. also if you add 1-2 tbsp per gallon of dolimite lime to the soil when mixing it, you will have much more stable ph throughout the grow. a must if using a peat based mix imo. good luck!

[Methyl3]

If you were to ask me I would say your plants look to have K deficiency. If I recall correctly (been out of the growing game for some time) this will possibly induce the "PITA to stay lit" syndrome. In other words...ever get that pot that never stays lit unless your pulling on the joint?!?! Thats usually a K deficiency in the flowering stage and leads to plants looking the way yours does. Check soil PH and make sure you have no bugs...if all is good then supplement with a good fert that is higher in K. Could also be a slight Mg deficiency, but looks more like K.

[slowthestone]

. also if you add 1-2 tbsp per gallon of dolimite lime to the soil when mixing it, you will have much more stable ph throughout the grow. a must if using a peat based mix imo. good luck!

I found it's a good thing to sprinkle a light amount of dolcimite towards the bottom of a container. Dump a few inches of soil, then pepper the lime around like Jimmy sprinkles! As the roots decend, and the acids sink...its a good way to prevent acid build up at the bottom of the container tween flushes.

Hi TAYLOR

For somebody that does not own a PH tester.. your grow looks farging great.. You dodged a bullet by even making it this far.. as JDOG said.. DO NOT ADD anything...

Who knows what your problem is.. since we dont know the PH...

It could be anything...


GET the 5 dollar PH tester NOW.. : ) it is worth every penny!!!!

Having a basic understanding of PH is the corner stone of GOOD growing...
PH is easy.. PH is your friend...

you want a tester like this...

Dude!
I feel like you are so close to harvest you should just flush,no nutes and keep check on the trichomes! You'll be fine!

Hows the temp in your grow room? getting enough ventilation?

[taylor324]

got the PH test kit... gonna use it from now on!

temps are around 75-80 i think. as much ventilation as i can possibly get.

more pics soon

thanks everyone!

[Opie Yutts]

Soon, you will get a PH meter, my young apprentice. You will quickly tire of the test kit process, and come to realize that meters aren't that expensive after all.

Are these getting enough Qxygen?
