Different issue, split from nitrogen or magnesium def?

[Guest]

I have 5 Satori and 4 ThaiTanic in the picture below. They sprouted about August 8th, plus or minus. They have been under 12/12 from sprouting. They are about 51 days into flowering. 72 days overall.

I don't know about the thread starter's plants, but I KNOW after much thought and review of my care, that my plants were/are suffering from a lack of Nitrogen. Not a shread of doubt in my mind now. And it's not much fun. I somehow also got my soil too heavy and so I can't water in any N very easily or very often. Not that I will now because it's really too late.

The problem began exactly as Khaleel's plant. Gradual yellowing of lower fans, spreading upwards as the plant consumes itself.

Y'all can say what you want, but I'd bet money his problem is lack of Nitrogen. Better get some N in those girls is my advice...and sooner rather than later.

The following pics were taken early on in the process

mtweedman: thank you for the input and pics, my friend. that does sound/look exactly like mine...

so your soil was heavy? were you overwatering? i've been drying them out today, then tomorrow was going to flush with a 1/4 veg fert solution... mainly just to clean them out and give them that dose of nit. only three of the twelve have started to yellow much, so i think i can stop it before it gets too bad.

thanks

Hey Khaleel:

Your welcome. I'd hate to see you go through what I have the past month.

The quick answer is yes to overwatering...in the sense that if your soil is too heavy and doesn't drain well...like mine. More on how that happened in a minute.

I also underfed them early on. First, I was using PureBlend Pro which I hadn't used before. Second, I deliberately held back N on the Satoris because I had read so much about how nutrient efficient they were and not to overfeed them, etc. BAD mistake. They still have to have N in addition to what's in the soil. And remember I made my soil with less Hi N guano than I normally use. And that mistake was compounded by my using PBPro wrong: I used 1/4 to 1/2 recommended strength since I wa sused to doing that with chem ferts. PureBlend Pro is meant to be used as directed on bottle with weed.

Back to the soil and overwatering. I may have been and probably was toasted when I made up my soil when I transplanted the last time. The initial batch of soil was a Promix based mixture and had a fair amount of perlite in it...to which I added more perlite because I like light well draining soils...even if I need to water more often. Anyway, the second batch of soil I made for the last transplant to the 4 gal pots was made with a local/regional brand of potting soil. It has only 5% perlite as it comes from the bag. Previous versions of this same brand had 20% perlite as I come to find out just recently. And being wrecked I think I may have measured wrong, or something because this soil is not losing moisture very well. And to complicate things further....I noticed that the root structure on my plants was NOT too snappy when I cut open the 2 gallon pots. Poor root mass means in what amounts to "too much soil" means the soil will stay wetter longer. The plants don't have the root system to uptake moisture. So you see I made a host of errors. It's a fookin wonder these plants are still alive....a testament to how tough weed plants really are Both strains continue to grow new calyxes as we speak. The Thai colas don't look too bad at all. And the one short Satori pheno is looking OK. Not nearly the damage on her for some reason. Oh, and the Thais didn't suffer as much I think because I fed them more early on when I was withholding from the Satoris.

I hope all this makes some sense. Learn from my mistakes I need to get off here soon. I have to get up early for opening day of elk/deer season I just hope I don't walk up on a big griz. Some guy hit one with his pickup truck Thursday not far from here...a big grizzley boar weighing 700+ pounds!! Killed the bear ands totaled his truck. He was lucky to be not hurt bad. I drive that road all the time and it has a 70mph speed limit. Hitting a 700lb animal at that speed is not fun.

Until tomorrow!

My haze babies are looking OK so far though

 

[khaleel]

right on, MT. i use Sunshine 4 soil (from the hydro store), and mix a full bag of perlite in on top of that (usually close to 60/40, this batch was 70/30 at the very least...). my main problem was that i had five one gallon bags stacked circular in one large, clear round drainage tray. i use a shop vac to get out the excess water, but the water in the corner wasn't draining out, and since i never pulled the trays out i didn't see it (1 gallone bags are about eight inches tall). hopefully now that i poked more drainage holes, put them back in the black trays with more room and better drainage, and let them dry out nice and good for a day, things should pick back up and i can take care of the nute situation. (they weren't getting enough of the bloom fert for sure... i'll up that and give them a little grow fert for nitrogen just to be safe.) the buds are still looking good but i would hate to lose quality or weight.

that haze looks great. and Satori is one of my favorites. i used to live in cali, and one of the medical dispensaries in Santa Cruz (the Napa Valley of pot) had Satori. i couldn't get enough.

good luck with the hunt. elk steak are fantastic i must say. but look out for da bears man! haha laters

I split this from the other thread as it is a totally different situation.

Yes, on first look the plant in the first photo is showing top>down yellowing and is showing an N def, however this can be caused by several factors.
Anyway, it would be good to have more complete information about the grow.

Please see this thread for suggested info we'd like to see given.

Started seedlings immediatly on 12/12 light from germination ?

MTWeedman- the last pic on the first post- couple Qs. Does that pot have a built-in drip tray? RIP IT OFF if it does; those things get clogged and KILL any drainage you may have had. Also that plant looks too big for the pot- I understand and totally agree with what you are saying about getting an optimal amount of root mass in your given amount of soil, but that one is DEFINITELY ready for a 3 gallon pail.
Giving N is the obvious solution but until you fix the excess moisture situation the plants simply can't uptake it effectively.

I suspect 10K that the guy was right.....

this is probably not top down yellowing but rather the last of the large leaves are at the top and they are yellowing......

Without some individual plant pics its hard to tell.....

n def plants dont really yellow from the bottom up.....


they use the large fan leaves from the bottom up......


the smaller guard leaves will remain green while higher fan leaves yellow......

Now that they're into 61 days flowering, can you give us an update MTweedman ?
How about a picture of the plant in your first pic (which was 51 days then)

ps. I disagree budly, if everything else is right with the plant (ie nute uptake etc), then N defs DO go from bottom up, but now they're well into the stage where yellowing off bottom up and overall color changes on bud leaves is very natural and to be expected.

The top down in that picture is more of an overall nute uptake problem, than an N def.
I suspect that since MTw got the watering under control the nute uptake fixed itself fairly quickly.
And now at 61 days into a 72 day strain, we should be seeing quite normal color changes and nice buds nearing completion.

Anyway, looking forward to some nice bud porn pics of these plants MTweedman

===========================================

I would have to see pics of the individual plants......

WIthout pics its hard to argue the point....


My guess is that about a week after the pics one plant at least was a bud on a stick....

Back in the overgrow days.... my general philosophy was to add N if needed to week 4(Nitrate N)..... after that I recommended adding N to your next grow......LOL....


However.... I wasnt of the opinion that adding N for a week or two beyond that would cause a disaster either......

Canna for example uses pretty high levels of N in their flowering ferts....

I have seen many plants outside turn yellow when I know there is N in the soil.....

this is because during heavy flowering its much easier for the plant to translocate N.......

But I also believe if the plant runs out of large leaves to use.....

its probably somewhat detrimental to the plant......

Hey, I'm not knocking you or anything Budley. But there is something in common happening in both cases, that being the overwatering screwing up the overall nute uptake, thus forcing the N (and other) defs...leading to the translocation 'consuming it' as you say.

The only one photo of the three in you gallery that isnt hps lighted, is one beautiful plant btw. How far along flowering is that one btw (days of how long a flowering strain) ?

That plant is my LUI moma..... the other plants are its clones for the most part.....


I pick LUI at 9 weeks........ this one is without large leaves to see the bud structure.....


ie....was being picked.....

I dont do many pics.... someone asked for some......

I had a grow faq on overgrow and my hand is now all over the internet......

such is the price of 'fame'......

By the way 10k that quote came from mtWeedman about consuming......
