2 Strains - Same problem - Lots of pics and info! HELP

Seems like im always perfect up until the time when you start thinking of harvest. Always something different, Ive looked at hundreds of sick plant pics and thought i knew what to do. Ended up flushing anyway so please help...

Plants are about 5 or 6 weeks flowering, been on 12/12 since seed under 400w hps.

Soil - Fox Farm ocean forest in 2.5 gallon pots.

Nutes - Fox farm trio. (used 1/4 nutes for the second time on friday, noticed they got worse so i flushed yesterday 4-4-11.)

Water whenever pots are super light with phed tap water thats been sitting for 24 hours.

Please ask away if more info will help me know what to do right now before they go to hell. Thank you in advance.

unless I am missing something, ur plants just look like they r becoming naturally at this stage nitrogen deficient. u said 5/6 wks flowering, how much longer ur have left? all the fan leaves could be completely yellow upon harvest & it be perfectly normal. if ur ph is on track & ur feeding ur k nutes mix like u r, u shouldnt be alarmed. r u also using any cal/mag type nutes? they tend to get that deficiency during flowering as well but I dont see any signs of that in ur plants.

Yes i did add 1/4 dose of cal mag when i fed them last. And thats what i thought at first but it seems way too early for so much of the plant to start becoming N deficient, i was expecting another 3-4 weeks at least. Havent even thought about a final flush yet because the buds still have to fill in a bunch. Just worried that if i dont fix this problem i will have to end up harvesting early.

Now that i look at the pics its hard to tell how bad it is, the 3rd 4th and last pic i think are the easiest to see but its alot worse looking in person and is already spreading to the top fans.

dont stess we all grow for bud u are allready over half way and if there was a problem your to late now. just keep doing what your doing not all clones are 110% the same aslong as ya bud aint fucking up dont stress the lower leaves will do that and sometimes move up a few nodes if the start to die let them just fucking chop em off whats the worst that could happen

It could be any number of problems, these are just examples I found, the first one is a potassium deficiency, the second is zinc deficiency. I go to this website when I'm trying to figure out nute problems. Hope this helps, good luck

Yo dude thats over fert problem, i wish i had done some pics and a small guide on over fert in flowering as mine would look like yours! You added fertilizer and it got worse so you even said it but didn't realise it. Don't add ferts for a couple weeks and water so that you get a good amount of drainage at the bottom of the pot like a light flush. Seriously this is over fert, how long in present soil? what size pot? how many weeks before you fertilized soil first when repotted to present pots? what soil brand and make is it? Elfrogger it definatly ain't potassium or zinc and he is using fox farm soil and nutes so ain't gona be deficient there! Damn that bad advice elfrogger! Sorry dude.

Ok... First of all nice job. You are in the last stage of flowering... its natural to have yellowing in the leaves when you are that far into flowering. all the stored nutes in the fan leaves are getting used to make those buds grow. I sometimes wait until the leaves turn all yellow & fall off also i stop flushing a few weeks b4 i harvest bc it dries out and cures faster (it allows the THC to decarboxilate which converts the THC into a number of cannabinoids and thats what actually gets you stoned). No worries my man. you got a good looking successful grow. you'll start to notice how dense the buds get as the leaves turn more yellow. hope it gets you fried

Hey that don't look like nitrogen deficiency which you get at the end of flowering! Fertilizing made it worse! And the fact that it only happens after you fertilize says it all. Look dude it is over fert i'm certain, purple stems and burning leaves is over fert 9 times out of ten, sure you looked at a lot of pics and couldn't work it out and over fert is why. All you'll notice is it gets worse and your bud suffers, stunts and takes longer to finish as well as longer to dry when cut and hardly much smell except when you handle them on the plant, weed smokes a bit funny tasting.

Thank you all so much i didnt even check back until today because i assumed no one would answer because its kind of a stupid problem. I wish i could give rep to all of you guys... But I thought it may have been over fert too, the thing is the problem started before i added any nutes so I thought she was hungry looking like she did. So i fed them and the problem didnt get better after a few days so I flushed. I understand that its close enough to harvest and i am just gonna roll with it and let her do her thing. My past few grows have just been perfect, like i had no problems at all i couldnt fix. But when it came to this i looked at pics of sick plants it seemed like mine had every symptom. I didnt know where to start after flushing them. I think that the plants being in the same pot most of there lives didnt help, especially because there only 2 gallon pots i believe. I normally would have put them into 5g buckets but they were 12/12 from seed and not so big so i figured id save soil. But thank you all again, I know its so easy to see that someones freaking out over nothing. But if your the one freaking out sometimes all you need is someone to tell you to relax.

This guys advice is so fucking way off!!!!! It is NOT natural for a MJ plant to yellow and die off during flowering. Simply a myth that lives on because it occurs so very often. Very, very often. Sorry but it is not 'the plant doing it natural thing'. Its the growers failure to maintain
a happy, healthy and thriving plant. Instead its a a slow, starving dealth at a period in a plants when its putting on most of its weight and resin. Your plant shows sign of a ph shift and deficiency both of which have nothing to do with the plants 'natural and normal' life cycle.

It certainly can be a zinc/potassium or any other deficiency FoxFarms or not. And sorry Kinggrow but you are the one giving damn bad advice. Ef was actually pretty close to right on.

Tru dat playa.
The plant shouldnt yellow untill you start flushing with plain water at the end. Thats when the plant will use up the nutes in the leaves. Im doing a little research on feeding calcium carbonate (not nitrate) all the way to the end. The tobacco companies did research and found that keeping up with the calcium to the end would make the tobacco leave a white ash and not be harsh. Gonna try it on a few plants this harvest.

ur entitled to ur opinion...while yes, many plants r vibrant green until harvest, others fan leaves r completely yellow, while the buds r green & full. I have seen the most beautiful plants at harvest, both with completely yellow or green fan leaves; both having reached their full bud potential with wonderful full colas. every strain is different, AND it is very difficult for most to maintain the perfect balance in plants, where as the transition from providing enough N, to cutting it back so it does not impede flowering. Rarely have I ever perfected that perfectly green plant to harvest. I didnt say it doesnt exist or cant be accomplished but like u even said it happens more often then that, so in that respect, I classify that as normal. Again not necessarily the way it should be or could be, but the way it most often is. and in late flowering it is hard to overcome the deficiencies that weren't addressed earlier. and again, I said IF the ph was on track etc. when I answered the first post.

So cowboylogic you say ph is the culprit, hmm so whats the remedy at this stage of flowering on his plant and what can he do to stop it happening again?? I never really had ph problems in my soil, i use to measure but got bored of seeing the same result in runoff. I can take what you say but can this guy see results soon or what. I use to post on here but forgot account details over time. Just finding recently that my soils are so high in nutes and keep the ph well that i barley have to use nute whatsoever and found that every bit of advice for any of my plant problems seemed to point at adding more ferts when in reality this just burnt my plants more. Naturally i came round to leaving the fertilizer out for most of the grow and i never had the problems again, they just went away over night! I suppose i'm wrong suggesting nutes but if i rephrased it to nutes/ph/watering/humidity (and everything else but add more nutes as so many people suggest) wouldn't more growers problems be solved than just adding nutes?? I feel betrayed by a lot of soil companies for selling me such hot soil and had to change a lot about the way i grow to deal with their mixes.

Ole cheapo's 2 cents worth here .... screw fox farm... I have wonderful results with cheap ass miracle grow potting mix ( not the soil ) ... usually get a touch of nute burn in the first grow on it ( 1 good flush corrects it ) and then its friggin perfect from then on ! You can even pick all the the little round balls out of it and be good from first run on it , but its a pain in the ass and a good flush is so much easier lol anyway .. after the first run your in control of the nutes and cheap ass miracle grow fertilizer takes over . Just make a very light mix for the young one's and slowly introduce more . Miracle grow bloom for the flowering ... Bam...

Wait i just hit on somthing, did you say pick little round balls out?? i have noticed in the last year one or two different coloured balls in my soil mix, very small, size of a mj seed aprox! Is this how they time release, it seemed very hard and not like time release i seen sold in the store. Hmm is my soil company ripping me off with time release and thats why the high level of ferts and to top it all of in my local asda they are selling westland compost with fertilizes for four months!! Four months are they taking the p!$$ or what. I did a lot of research of my soil company and they swore blind to me that they weren't banging any harmfull chemicals in their soil and it was all from a base mix not little round balls. Then again they could be nothing. Im gona sieve my soil see what i get now!

Listen to TheException, prob N def. Just a normal part of the late flowering stage I believe. Could use a shot of Grow nutes with high N if you have another 2-3 weeks of flowering left.

no. you dont want N the last 2-3 weeks of flower.

Plants shouldnt be green untill harvest, You want your plant to use up the nutes it stored in its leaves when you begin to flush, turning the leaves yellow, BUT NOT DYING OFF! If the leaves die off, then you are starving your plant. The reason people think it is "normal" to have leaves yellow before flush is from bad information.
