Ok so just recently the flowers stated turning yellow on the outside.
By looking at the pictures is this nutrient def. or is it over nutrients or is it because its too hot in the res. the temp hardly goes over 80 F?
Any help please I dont want my grow to go to waste. What should i DO?
What is your experience level? first time grower
Your Equipment:
.1) Type and wattage of lights. Using HPS lights right now 400watts

That is just part of the plants cycle of life. You switch to 12/12 the plant thinks its life is coming to an end and it releases a hormone so it produces fruits and then it dies.

Looks like it could have a possible magnesium deficiency.

i second that mg def and your lights to low dude a 400 hps have it 10 -12 inches:thumbsup:

Third on the Mg deficiency, and I think too close to the lights too,,,,about a foot

Looks to me like underwatering and overfeeding. Is watering twice a day ok for coco or rockwool? Not being a hydro guy, I'm not sure.
Did someone recommend these products as a good nutrient system, or did you just go online and throw-together stuff that looked cool? (serious question) Advanced Nutrients is great at marketing, but don't fall for all their self-hype. Their shit isn't any better than other, cheaper brands.
Hey guys...do this guy a favor, and look-up the ingredients of his nutrients and additives before offering advise. 4 out of the 4 products he uses has plenty of magnesium. (too much)
Heck...Connoisseur A is a fake CalMag product.

Rusty, I will do that....but he could still have the deficiency due to a lockout. I, like you not into hydro and probably should have kept my mouth shut
Rusty Trichome
05-30-2010, 01:08 PM
I understand the lockout possibility, but if we give the impression he is lacking magnesium what do you think he will want to add? Sometimes it's a pain, but if we want to give advise, it might as well be good advise. :thumbsup:
Sometimes it takes a little work to actually see where the problems lie. I had no clues about his nutrients till I Googled 'em. Didn't even know they were Advanced Nutrients till then.
Speaking of which...This situation is the main reason I distrust AN. A bottle of crap for every situation, another bottle of crap to correct issues caused by the first bottle.
Although their labels look way-cool, and they came up with a couple of cool names for their products, and everybody is elated to spend their parents cash in an attempt to claim they use "the best, most expensive" nutrients available...it's still mostly molasses derivatives, urea derivatives, or magnesium sulfide derivatives, all at a premium price. (I'm using generalities here)
From what I've seen, their company stands for everything cannabis users have been fighting against for the past 30 years. Is a well-label product better than a well-designed one? Is a bitchen name more effective than a quality standard? Is paying top dollar unnecessarily, doing anything for your ladies? Is it worth the extra monies to "look" cool?
Keep it simple, keep it cheap. You'll thank yourself later.

It's normal for the leaves to start dying at the end of the cycle. A lot of people start to pick off the leaves that have started dying because the plant is using nutrients that are in the leaves, it doesn't really need the fan leaves at this point in it's life. By picking the leaves you might help the flush... which it's about time to do 2 weeks out anyway.
I would guess Rusty is wrong about them being underwatered and overfed, because it would have showed up earlier, not just suddenly the last 2 weeks. Not to say they aren't overfed, but that's not causing the issue you asked about... That said, I think the AN nutes are too rich in Nitrogen and I wouldn't use them to flower. You need nitrogen to flower, but at decreasing amounts as they progress. You can't do this with those AN nutes. But, I'm also a soil grower, so IDK...

You should have added this disclaimer before posting your guesswork. ^

If it doesn't need the fan leaves, why is the plant scavanging nutrients from them? I say you're assumption is wrong. Pick off the fans prematurly, and you risk nutrient shortage and the problems associated with underfertilizing and the stress that injury revovery induces.
When you flush, you are flushing the nutrients from soil, not the plant. Leave the leaves alone for beter results.
I would guess Rusty is wrong about them being underwatered and overfed, because it would have showed up earlier, not just suddenly the last 2 weeks. Not to say they aren't overfed, but that's not causing the issue you asked about... Ok. You've read the issues, conditions, and have seen the pictures. Tell us...what is your diagnosis and remedy, oh wise one? Exactly what is causing the issues asked about? ^
That said, I think the AN nutes are too rich in Nitrogen and I wouldn't use them to flower. You need nitrogen to flower, but at decreasing amounts as they progress. You can't do this with those AN nutes. But, I'm also a soil grower, so IDK... So, now you think too many nutrients and likely inappropriate nutrients. WTF do you think I was saying...?
Used to tick me off someone chiming-in without the knowledge nor experience to know what they are posting. But now...I must say...it is amusing watching you try and follow me around "correcting" my advise. I don't think you're doing your image here much good though. What with sticking your foot in your mouth with every attempt, and attempting, what...? Payback? I may not know hydro specifics, but I do know plant biology and specifically, growing quality meds. Were I you, I'd learn the craft before attempting to instruct other's.

Rusty, maybe this should be your own private forum, lol!!!
So how are your yields Rusty? I've gotten 3 lbs/1000W in more than 1 system. I've been doing this for nearly 20 years. I've set up dozens of spaces and helped several dozen growers fine tune their systems.
I'm "following you around?" You post in every thread in this forum. Give me f'in break dude. Thats ridiculous, don't flatter yourself.
Now to address your concerns, your answers to my post tell me you don't have NEARLY as much experience as you THINK you do...
-Yes, I think the AN Nutes have too much N, looking at the formula and looking at the OP's plants, but IT'S NOT THE CAUSE OF THE OP'S "PROBLEM". Which isn't a problem at all, it's just how they grow.
-If you want to argue about defoliation, I suggest you do some research and see what the REALITY of this technique produces. Here's a start: (sorry if links to other sites aren't allowed, IDK)

https://www.icmag.com/ic/showthread.php?t=174163
Now, k33ftr33s isn't getting my yields buy jrosek is beating me by around 25%. And they defoliate WAY more than I do. I just use it as a part of my training routine.
- I already gave my diagnosis and remedy. Start flushing to get rid of the excess N and chemical nutes, and pick off the fan leaves that the plant is discarding anyway.
I can't f'in believe you just posted that crap to me. Seriously, WTF were you thinking?

I've set up dozens of spaces and helped several dozen growers fine tune their systems. Your half-hearted advise isn't supporting your claims. You come in here saying I have no clue (paraphrasing) yet offer the same advise I was posting. WTF?
Helping other's set-up their systems...? Bummer...all I do is sit here, stomping on ego's and pretending to know what I'm talking about.
I'm "following you around?" You post in every thread in this forum. Give me f'in break dude. Thats ridiculous, don't flatter yourself.
Whatever. But actually, you flatter me with your negative rep. Makes me feel all warm-n-fuzzy inside. So if it made you feel better, have at it. I've been negative repped so often I almost expect it when I log on. :jointsmile:
Now to address your concerns, your answers to my post tell me you don't have NEARLY as much experience as you THINK you do...
-Yes, I think the AN Nutes have too much N, looking at the formula and looking at the OP's plants, but IT'S NOT THE CAUSE OF THE OP'S "PROBLEM". Which isn't a problem at all, it's just how they grow.
Gee. Guess I missed the class recommending overfertilization and an improper nutrient regimin. Anyone else curious what this will smoke like if left for a couple more weeks?
About yield, I grow enough for my wife and myself. Beyond that is really, none of your fucking business. And seriously, I have no care what a commercial grower nets. It does remind me why I started growing in the first place. Too many growhouse gardeners putting out quantity over quality at scalpers prices.
-If you want to argue about defoliation, I suggest you do some research and see what the REALITY of this technique produces. Here's a start: (sorry if links to other sites aren't allowed, IDK) Actually, the argument rages on despite your "proof" otherwise. And yes, I do try and stay abrest of factual advances in botany. But I'm also wary of bullshit. If you are refering to picking dead leaves off, no problem. But stressing a plant by pulling active fans in flower is unnecessary and potentially harmful.
Trim Fan Leaves? (http://www.greenpassion.org/showthread.php?t=14546)
(from that link)
"Deb is right. The fan leaves are the food factories of your plant. Look at the structure of your plant. Each branch is fed by a large leaf. Every little twig and bud has its own feeder leaf. I never remove a leaf unless it is badly damaged or more than half yellow.
More leaf area equals more food for the plant.
And if you aren't happy with the smaller buds at the bottom of the plant, just harvest the larger top buds and leave the little ones to fatten up for another week or two.
Granny"
Now, k33ftr33s isn't getting my yields buy jrosek is beating me by around 25%. And they defoliate WAY more than I do. I just use it as a part of my training routine. And your training routine includes trimming active fans in flower...? Have at it.
- I already gave my diagnosis and remedy. Start flushing to get rid of the excess N and chemical nutes, and pick off the fan leaves that the plant is discarding anyway. I know. But hmm... Guess I misread you. Could have swore you slammed yet re-worded my response and mentioned he could use a flush in a couple of weeks per schedule. The first part was technically fine, but the combination of nutrients almost balanced-out the N-P-K numbers, depending on solution ratio's of each) Waiting to flush is sound advise if you want your meds tasting like straw. Do you think that's wise advise? Personally, I was waiting to hear more from the OP before recommending further action, but an immediate flush is in order. But, we've likely scared him off by now.
I can't f'in believe you just posted that crap to me. Seriously, WTF were you thinking? Funny...I was thinking the same thing.
it's "others" not "other's"
Bummer. Hooked on Phonics was my favorite class, too. :jointsmile:
BTW, How's This? I guess I have no IDEA what I'm doing....
And I guess I'm in the dark as well...
Below is a 10 gallon pot, PokerFace - 7 weeks. It's an original pre-release Cherry Bomb strain I've been breeding for many years thanks to Reeferman, who provided the seeds. Went 8 1/2 weeks. Yielded about 3 to 4oz dry, but this is a re-veg, and was under 400w x 2. ;) Sorry, wasn't expecting to provide proof, so no post-harvest pix. :cool:
I'm sure the other members appreciate any useful information you have to offer, as do I. But if you're only going to give half answers, or not read the thread (your ph issues post we already discussed in another thread) then it seems to me you are not helping at all. I guess perfection is too much to ask for, but let's not miss the mark too often, huh?
