HELP!!! Rep+++++++

[AllenHaze]

I'm not sure how it is possible for you not to be able to see what I'm concerned about unless of course you are visually impaired, if that's the case excuse me if I came across rude. "Brown chlorosis" is chlorosis that is brown if that helps.

OK, now we're talkin'. I thought my color profile was off. I DO see brown in there and I cant think thats any good. New growth is a nice bright lime green. I've never seen the brown in there before. I'm a lost ball in tall weeds on this one.

Thank you. That is exactly what I've come to believe about the new growth being lime green. Thanks for your time anyways.

Its from being too cold, it will clear up on its own, probably noticing slow growth also? how do the pots feel? just because the canopy is warm doesn't mean that there isn't a cold draft at the floor. I had to put a towel at the bottom of the door to stop the draft.

The affected leaves in that pic appear to be yellowing. I have no idea what the color profile of the image you have gotten off the internet is, but color can be really hard to discern on a monitor.Chlorosis by definition is a lightening or yellowing of the leaves due to a lack of a nutrient, most commonly nitrogen, but other deficiencies mimic this as well. I don't see that as chlorosis. THAT is most definitely brown. My monitor aint THAT far off.
As to WTF is wrong? Dunno, but i'm sticking around to find out!!!

If you want to see "Brown chlorsis" what ever that is, then by all means, you have a one of a kind super BC plant....
I see new growth...
Lime green fading to white green green on outside...
You see brown ? Then WTF did YOU DO one week to 10 days ago?
I don't see brown, so I don't wonder.../\ what did you fukk up, change, move add or what ever... you caused this problem, now, I ask you what did you change 7-10 days ago?
What did YOU do?

Checking what I've done in the past 7-10 days is exactly what I've been doing in times like this. It's what I recommend to others as well. I've done nothing differently aside form moving them into the closet, the closet has a minor draft but the hot water pipes run right through it so it still gets pretty warm. Watered the same. I added some blood meal about 10-12 days ago but a very small amount per plant like maybe half a m&ms worth for each plant seeing how it is FFOF and they are less then a month old. I watered once with molasses two weeks ago just to try it but nothing really happened so I moved on. I topped them just before this happened but...it also got unusually cold that night so not sure if the draft was worse and the plant were also more susceptible due to the topping. You see, I would not come on here asking for help if I hadn't already spent hours searching for information on this on my own. Thanks.

That wasn't directed at you. Sorry if it came across that way. lol. I was under the impression that chlorosis could apply to any health related discoloration as well. What is the proper term for that? Is it just called "discoloration"?

 

[churchhaze]

It's funny because the first thing I thought when I saw the plant was maybe it had sulfur deficiency, but then thought that was crazy.

If it really is, some Epsom salts (magnesium sulfate) would help.

 

[Bugeye]

Just curious , how much molasses did you use? Molasses is primarily food for your micro-organisms and not your plants. I use it at about 1 Tbspn per gallon of aerated compost tea.

I really have no idea if this is related to the browning, but if you put a huge amount in it could be worth exploring.

 

[AllenHaze]

I used a tbs per gallon. I only watered with it once before dumping it. I'm hoping it's a cold issue, I have a heating stone out at the farm I might grab and throw under the pots. Thanks man.

No worries man, I didn't think that at all. I'm intrigued as all hell now. Cant wait to see all the responses!! LOL

For those that think this is normal new growth, I'm sorry but how do you see that?
There is clear purpling of the midrib and slight chlorosis from midrib>margin. That is not the slight yellowing that is associated with new growth. He's barely been feeding her, why is it crazy that it would show signs of a deficiency?

OP, below is an early Xmas gift(if you celebrate it) from me to you. It's your new best friend in situations like this. Although it may not give you the answer you need, it is an excellent starting point.
As for the chlorosis thing, chlorosis=lack of chlorophyl. Which is where the "chloro" prefix comes from. Necrosis(necro=death) is the browning/dying of leaves.

Look into mobile vs immobile nutrients. Mobile nutrient deficiencies show up in new growth so start with those. Keep us posted though, it may not be bad.

Also if anyone else disagrees with what I have said, please support yourself with references. I have mine if you wish. If you cant see that discoloration you need an eye exam though

 

[big bud 56]

drop it dude,if you find another reason why it looks like that then don't show us a chart,find some pic samples.
I would just let it grow and see what happens.
Move on and look,listen,and learn.
Peace

http://dnr.wi.gov/eek/veg/trees/treestruecolor.htm Read this. I'm still trying to put it together in my head but here it goes: The lights in my room are on for only 14 hours a day as per recommendations to promote an increased F:M ratio. Soil is also cooler then the ambient air temperature unfortunately, I'm assuming lowering the overall temperature of the entire plant as well. Chlorophyl and caratenoid are present in the plant all the time but chlorophyl covers the carotenoid. Here is where I think it might apply to my situation: Cool temperatures and short days trigger a decrease in chlorophyl and carotenoid starts showing through but then due to the bright days in my grow room (10 cfl 1600 lumen 6500K in 2 square feet of floor space) and the presumably cool nights in my closet seeing how the soil has been cool it has resulted in my baby producing anthocyanin. Last night I added insulation to the bottom of the box hopefully this will allow for more heat to reach the pots. This morning the discoloration has lightened some. The box isn't cold at all during the day, the closet is wide open and the box is inside with a baseboard heater running right through, thermostat is set at 78. Also there is the "thermic cooling effect of sweating" I was reading in one of my grow bibles (thank you Kat!). I am still piecing it all together but I figured I'd throw what I had on here and maybe you guys could paraphrase and edit and add your own experience to come up with a better explanation. I'm not jumping to any deficiencies just yet, I suspected cold from the start but didn't know why and had several people telling me otherwise. Thanks again for your support.

I can appreciate your laid back attitude but I'd rather figure out why this is happening. It would be pretty ignorant of me to simply sit back and watch to see what happens rather then studying an identifying the problem. I guess I'm just one of those guys. Thanks though.

Also, Crispy Bacon thanks for the chart I've def seen it in one of my books but just skimmed past it at the time, now I'll keep it close, maybe print it out and stick it in my grow area (away from prying eyes of course) I was already aware of their definitions but I def incorrectly assumed that browning could be chlorosis as well as opposed to simply being relative.

 

[Jack Harer]

AllenHaze, the necrosis Crispy is referring to would be necrotic tissue, and that wold be dead "Crispy" tissue. It will not regenerate. Chlorotic tissue on the other hand is still viable and will regain it's color if what ever caused the chlorosis is corrected. I don't see the brown we're seeing as necrosis.

Here you can plainly see necrotic tissue on the leaf margins (one of my more memorable fuck ups!)

Good luck and I hope this gets figured out. I'm dying to know.

Why don't you look into mobile vs immobile nutrients? This is 100% WRONG. As far as supporting myself with references, do your own research. This is such a basic fundamental of plant physiology it is obvious you have no clue what you are typing about.

OK, since it's probably impossible for you to be wrong, here is a reference from someone who has knowledge and credentials:

http://msucares.com/pubs/publications/p2760.pdf

So you say you got references? I'd be throwing those things away before they cause you to spew further misinformation.

 

[AllenHaze]

Most discoloration that has not advanced to necrosis (burn, prolonged nuteburn etc etc) is relevant to chlorosis. It may not be termed chlorosis but as the plant is stressed for certain reasons, chlorophyl production is suppressed and carotenoid associated colors show through more. This is what I was talking about (though at the time I didn't know what carotenoid or anthocyanin was specifically) "Necro" is a very common prefix. Thank you for clearing that up though. I'd really like your take on what I posted a second ago JackHarer, you must have been around awhile so you input would not be taken lightly. Anthocyanin production is what growers are encouraging to promote crazy colors in late/post flowering period (I'm sure you already know). Thank again!

Thought I'd add that it's officially a she. She is only 25 days old!! This one was the fastest growing of the bunch as well so I thought it was going to be male. Nope wispy, carpet hairs all over the place (lol) YEA! I'll admit that I'm even more nervous now, This is only my 5th grow and the first to maturity indoors. ALWAYS guerilla before. My last batch ended up being ALL males. 4 plants ALL males. The brown color continues to recede it remains only at the base of the leaves near the petiole. None of my other plants have started to show sex even some that are over a week older! Any comments on that? I'm guessing good genes,maybe a strain dominance that is better suited to my particular grow environment. Either way there is a GREAT chance I'll be making some fem seed with her (colloidal silver). 25 days???? uhns uhns uhns uhns! (flicking light switch for rave effect) The hairs are very hard to capture on camera but they are def there. Like little cotton fibers. Anyone read the link above? Also thanks aimaim that is exactly the kind of resources I "aim" to find. Wondering if it is common for seedling to develop these colors when they grow outdoors without any control for environment. I'll be checking other plants come spring time when we do fiddleheads! Come to think of it sometime the fiddleheads have funny colors. Hmmmm.

@AllenHaze- do you run your lights on @ night? this can help with temps and the cold nights. some rigid insulation foam on the floor could be a more permanent solution than a towel, if you get some with foil on one side, put the foil side down. hope this helps.
