Flowering 6th week Leaves turning yellow!! Help! Filled out trouble shoot

[Jmann567]

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:

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.

[xxxhazexxx]

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

[WashougalWonder]

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

[Rusty Trichome]

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.

[WashougalWonder]

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]

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.

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? ^

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.
