Plants dead by end of flower! What gives!? [PICS] help!

Hey guys, Had a major problem with my last grow. Maybe someone could shed some light on the issue.



Heres the set up:
1 x 1000w light in air cooled hood 3-4ft from plants
Plants vegged till about 12-16" height in 6" pots before 12/12
Room steady at 82 degrees
No moisture production (humidifier) for 75% of flower

Now they were super happy until about 4-5 weeks from harvest. The fan leaves started going yellow and falling off. Now all the leaves are yellow and it seems like the plants cant produce much crystal. Also about 4 weeks from finish they developed a nasty spider mite infestation. At first i tried to save them but just gave up due to their condition.



Its too painful to snip off every dead leaf so Im going to chop them all down and make hash out of them. So hopefully its not a total waste. I did lower the light to about 2-3 feet from the plants and thats when they started yellowing. after a couple weeks of that i moved the light back up because i thought i was killing them. Im not sure if thats a coincidence or the start of the end. Also after i put the cool air humidifier in the room it didnt seem to help at all. Also to note. The crystals didnt turn amber at all. I have a suspicion that they didnt have enough energy to mature to the final stage.



So Ive come to several conclusions:
A. Overheating and not enough moisture in the air, so the fan leaves died off.
B. The roots became rootbound in the small pots and the plants could not support all their leaves AND produce crystals.
C. Spider Mites caused damage to the leaves, preventing them from absorbing enough nutrients to support themselves.


C is highly unlikely because they started dieing before the mites showed up.
B is very likely because they ended up about 2-3ft tall be the end, and thats pretty big for little 6" pots. I intended to SOG alot of little plants in these pots but ended up vegging them too long.
Any thoughts guys?
Any help is greatly appreciated!

Edit: Ive harvested a few and when i take the earth out of the pot the roots have formed around the edges and are yellow/brownish. Also, the problem with reason A is that even after putting a cool air humidifier in the room and running it 24hrs a day the problem continued to worsen. Shouldnt that have alleviated the issue if it was due to lack of moisture?

i think its A

Has this happened to anyone else?

it would have to be one fucked up infestation to kill all those plants like that....

did u feed your plants at all with any nutes?

wow, the sight of that scares the shit out of me..on a good note i can tell u exactly what went wrong. your pots are too small and your plants are too big. your plants are root bound in other words. week 4-5 is when the growth begins and really kicks in about 5-6. you have tiny roots trying to feed a big plants, and the nail in the coffin is the heat, 82 is pushing it. i just transplanted some plants that got to big for their 3 litter pots, they started getting yellow because they didnt have enough roots structure to intake the proper amount fo nutrients in my 3 footers, the toher plants were fine, due to the, being 1/2-1 foot smaller. I'm doing top drip, in ebb & flow tables, 3ltr pots, pure clay pebbles, WATERING every 30min with 75temps and i still had this issue, imagine how harsh that would be at 82temps, with less watering (since your in spoil), with large plants and a small root structure!

solution: git 1 gallon pots, and better ventilation, and don't veg them so long

Omg im so sorry dude I cant believe that happened. Cant say what happened. Were you feeding nutes? Ive seen plenty of grows that seemed fine with big plants in small pots as long as you fed them well. I dont have enough experience to really say though.


Better luck next time sir. Hopefully RIU can figure out what happened.


Doubt it was moisture, imho, marijuana grows in Afghanistan like a weed where its a desert.

they looked severly burned. im guessing nute burn because its all the way to the bottom branches. all of them stems are brown and almost dried looking. they should be green. you got any pics leading upto this point?

with roots that size, it doesn't matter how much you feed it, it can only uptake so much. Its like a bodybuilder have access to all the whey protein and fresh spring water in the world, but he can only consume it through a straw. the plants are fine in the first 3-4 weeks because they are still transitioning to the bud growth stage, bud when they start trying to grow buds ur screwed because they cant uptake the right amount, hence no crystals, irregular or malformed buds, etc..

rootbound and nute lock.

it is possible to grow big plants in small pots.ive seen it done plenty of times.

Maybe they are Zombie Plants

And smoking them will eat your brains out

well im skeptical of that, not to mention the quality, and bud production....as you can see, technically so did he..

Thanks alot for the replies guys.
Yes it is quite depressing.
This was 3 months of my life
But im over it now.
Next time will be better.

Never Outgunned: After reading your reply it seemed pretty obvious it was due to the size of the pots and the temp/lack of humidity issue didnt help. Unfortunately that 1000w light is hot like a mofo. Even with the air cooled hood it heats the room up pretty bad. I just redesigned the airflow system though so it should be stable at 80 degrees from now on.

Also i got 8" pots for the next try but i think i will take them back to walmart and get the 10" ones. 10" is 1.75 gallon so that should be ok (better than the 6"s .34 gallon and the 8"s .75 gallon !)

Gonna look mighty suspicious returning 80 some pots but fuck them anyway

Try bigger pots and fewer plants. 1000w light source for plants you're growing in half gallon pots is shady. People can say "I've seen people grow 17 foot plants in a coke can" doesn't mean it's the smart way to go or the best. Go for at least 12 inch pots. It's worth the extra money and considering what you've put into the lights, the seeds, and your time, give them the room to grow. And I'd pop a bug bomb in there between now and your next grow also.

Switch to hydro bro, easier to control with those kind of temps, they will always have water, you can control nutrients easier, and they will grow much faster. i know that sounds like a pain,but once you do, you wont go back. i started out in dirt.

1000w aircooled 3-4ft away? Those plants look like they were ignored for 2 weeks. >.< Either way I am sorry for your loss, I would be pissed beyond belief.

My thoughts exactly! ha! so sad. but then, this is how we learn isn't it. Anyways it's def some root bound + sever nute problems, either totally burnt or totally starved. My first micro grow I succeeded in growing two plants in tiny 4" containers, they weren't very happy, but atleast they made it to the finish line. jesus.

I believe those containers are too small.

Not the container size. I know that every strain is different but I know mine could make it to 5' status in a pot that small probably.

No its due to the strain not handling the lowering of the light, and the heat it creates. Ive seen this prob a few times on here and happened to myself outdoor, this is the first indoor one.
Outdoor it goes like this ,plant is growing very strongly but when the light intensity pics up (mid summer) they yellow, brown and shrivle up and die in a week. Seems the plant has no resistance to disease including mites etc. Your plants died like this too bro(disease took over plant) but it happened late and you still got something ,the others and myself got sweet fuck all. Even if in the past this hasnt happened ,the strain is finished(maybe over bred)Get a new reliable strain next grow
