Little Bit of Yellowing Right Before Harvest

[snowman4839]

I've read that yellowing is normal toward the end of flowering. I'm 6 and a half weeks into flowering and they're lookin great IMO but they're getting a bit yellow on the tips of the sugar leaves up near the main cola. It's either N def. just cuz they've been flowering without vegging nutes for awhile now (just gave em a low dose last watering to help) or it's nute burn (which I think it is). Just to confirm either/or... take a look plz

Also around when should I look to harvest since this is like week 6 and a half? in like half a week to a week and a half?

btw...
400W HPS
2 Nirvanashop white widows
fox farms nutes trio
always pH'd between 6.5-6.8
11/13 light schedule
started flowering march 21? or 20?

A. You should harvest when the pistols on the buds turn more amber than white or when their all amber/red if their all red you went to far. (if your doing soil flush for two three weeks with sucrose/glucose based flushing stuff.)
B. That yellowing looks like nute burn more than not natural flowering yellowing if i was you i would flush with SUPERTHRIVE i <3 wal mart or home depot.

..Your ladie looks frosty and so f'n tasty ...im so jealous.....Good job...and is that little foxtail's i see

He didn't even ask for help with this but since you offered.......Get a microscope and harvest when you decide the time is right. If you are going to flush don't waste your money on shit to flush with just use water.

Its not N def your leaves are 2 green so that leaves burn just cut back a bit on the nutes next watering and see what happens with the worst case it continues and you have to flush with water to start over again. You are too close to harvest to be fucking around too much with them. You are so close that you might not even get to see any changes before harvest.

Sparkafire why are you so harsh on people!! Join in don't push everyone away, honestly and when you gona comment on my plants and problems, sure you seen the thread! Anyway unfortunatly sparkafire has pointed you in the right direction although quite sharply lol, and terror 303 was right too! Yer it just looks like a nute burn problem, it is good that you have backed of the nutes already and stay off them a little while, a flush would be good too incase of salt build up etc etc and to hopefully flush some extra nutes from the soil, yer plain pH'd water would be best here too.

You say you got a week and a half left but i say you got longer by the looks of those buds, they don't look swollen much or many red hairs, you could use a microscope to check tricromes but i would'nt worry bout that just yet as most bud should swell up a bit more before harvest. I know my strain quite well and it is white widow, quite indica dominant so when the buds have swollen and most of the hairs/75% or above have turned red on swollen calyxs and little or no new growth of bud hairs pretty much. I use to use a microscope but i can pretty much tell by eye now. Still best to use a microscope. If the plant was badly nute burned i wonder if it would prolong the harvest by some time as well? And the yellowing seen by nitrogen would mainly be on the big fan leaves not the smaller sugar leaves first.

Thanks terror 303. Lol I can't wait to lite up the first time in awhile with these babies...

Sparkafire - yeah I'm gonna hold off on nutes for a bit, maybe skip a nute watering and just give it plain pH'd water.

Yeah I expected it to be nute burn, I just wanted to double check since this is my first grow (or at least the half I didn't kill...). I just said a week and a half because that'll be week 8 and that's the minimum expected harvest time for white widow according to the nirvana site. Btw, since this is week 6, will i see much added weight to the buds in the last weeks before harvest? Or am I pretty much done with bud growth?

The color of the hairs has nothing to do with how ripe the buds are. Ive seen people say this a couple times on this site and its bad info. There are strains that keep the hairs white all the way through harvest. You need to check the color of the tric's

you can tell a lot from the state of the hairs....if you know what you are doing....how many strains stay white all the way through?

Sparkafire why are you so harsh on people!!

Bro I am not harsh on people I am a truth seeker! As you already figured out I do not like people giving blatantly false or misleading info. We all have different ways of growing and that's fine but when people make shit up or talk out their ass I take offense to it sorry man its just my personality I do try to be funny. I have been on here since June 08 and I can tell you that the crew that trolled back then was more like me and didn't take guys posting bad info, its just bad for the board. Also I need to change my avatar to a more warm a fuzzy one I really think it has an effect.

when you gona comment on my plants and problems, sure you seen the thread!

Yes I have seen them and I think those who had already posted, posted correct or helpful info and didnt see the need to add to it. I will look again and give you my take on it.

unfortunatly sparkafire has pointed you in the right direction

UNFORTUNATLY?! and in the right direction damn man thats harsh.

I know my strain quite well and it is white widow,

I knew I liked you That was my strain until I switched to a pure medical strain op.

Cheers sparkfire, i understand that some people post realy irrelevant misleading posts and some post the truth. You know when i started growing people told me the truth and i couldn't see it for the rubbish. I do feel that the right information for the plant problem is paramount as a lot more can go wrong with bad advice.

As for my plants i have lower leaf problems that sometimes seem to travel up the plant and slow the harvest but recently am finding my biobizz bloom is curing the problem, think part of the problem before was that i was then over fertilizing as doing a little with every watering for flowering period to cure this and getting salt build up and pH issues in late flowering. I have done two waterings with nutes and will just water plain water next time with a small flush planned in the next few weeks. Plants do look good now but i am not real sharp at noticing phosphorous and potassium deficiency, seems that as the plant shows the first few flowers i always get bottom leaf drop. White widow is quite a hungry slightly fussy plant, not the easiest to grow i suppose.

Anyway i just find that i like to harvest late when the bud has swollen to its max and at this point on my strain most hairs are red and whithered back into the calyx a bit. I don't need the microscope as i know when the plant is fully ripe and ready, most of my growth is done in waves of growth, by this i mean i get a lot of new growth and white hairs then it stops, these hairs go red and i'm like aha 75% red hairs i could harvest now but a few days later i get a load of new growth and the bud is all white hairs again. When the amount of new growth seems to be less than the hairs going red then i can start to see that the bud is finishing. I don't know if i explained it very well but this is how i know my bud is close to harvest.

How long do you think this guy has left in your opinion? do you think he has not counted the couple of weeks or so it might of taken to start flowering?

Im still looking for the name. I remember reading it somewhere. You should pay more attention with the color of the trics. They will tell you when there is more THC, or CBD, or CBN etc.. by the color of the trics, not the hairs. For instance THC will break down into CBD's, THC gives you more of a head high, while CBD's is more of a couchlock. You cannot tell this by the color of the hairs, only color of the trics

keep it up, you will learn..

How do the hairs tell the ripeness? Please, teach me. Clear trics means it still has more time, cloudy trics is when thc has peaked, and amber trics are degrading thc that turns into cbd.

How do the hairs tell me anything?

 

[Kingrow1]

Look guys your both right and both methods work. I use to use a microscope but dont bother now because i know when my bud is at peak ripeness by eye! Yes a microscope can look down at individual trics etc etc but when you grow the mj plant you notice the other signs of peak ripeness! Just the hairs turning red means nothing to me, i get red hairs from week 3 onwards and can easily see 75 percent red hairs at week 5, well that is till a whole new flush of flowers grow and then the bud is 75 percent white hairs again. The red hairs i am looking for are the ones that have withered and been pulled back into the calyx which has also swollen like there is a seed in it!!! When i get 75 percent or more withered red hairs and calyx swelling i know my white widow has reached a window of about one to two weeks where i can harvest. My hairs and calyx tell me everything and are exactly the same in maturity as the trics i.e. 75 percent red hairs and 75percent amber trics. Yes this is a fact for many strains although some might be a little different in some ways. When the flower can no longer be fertilized it gets old and the thc breaks down to other substances hence the amber colour of the trics. Now i can see my trics with the naked eye, my white widow is actually quite white near harvest funny enough, and each tric stands up tall and very visable, when 75percent of my trics are amber the whiteness of a lot of my bud has dissapeared and been replaced with lots of amber patches, yer i could g get my microscope but i would only see what i can see with the naked eye - lots of amber trics. Sorry that people seem to totally rely on microscopes because there are a lot of other signs and visable things which also correspond with the plant being at peak ripeness. Having a microscope helped a lot but in the end i never use it anymore and the bud is always the same.

So in conclusion withered hairs that have receeded back into a swollen calyx tell me that flower is ripe, 75 percent of the flowers like this tells me the bud is ripe and ready to harvest, use a microscope if you want but i feel that i can tell by overall appearence of the bud.
