this has happened before all my bigger leaves get discoulerd yellow sometimes even brown and crusty then all the little leaves die and im just left with the bud and it eventually dies as well i cant figure out whats happeneing. maybe its too hot since im having heat problems but ive had a lot of problems the last two crops and need some help.
Looks like some serious nute burn.... They look fried....could be heat stress....could be a little of both....
What are your light/dark temps? What's your water/feed schedule? Is your grow space completely dark during the dark period?

i definatly considered the nute burn but i dobtd it since it had happened before. my flowering light runs from 10:00 pm till 10 am and at night it averages around 80 but it gets hot as shit during the day and no matter what i cant keep that room cool so im not sure what its like when its dark. i water twice the nute them up on the third watering and i end up watering almost everyday. i had some light leaking in recently but i took care of that
If they're that big and you've gotten to this stage twice before, I dont think its your water.
You said its 80 with the lights on, and 'hot as shit' with em off. Try to keep the day and night temp fluctuation no more than 10-15degrees.
I think its from the heat when the lights off. Do you have it outside er sumthin?
Do you have an exhaust system in the tent?, if so just leave it on to suck out the hot air during that time
im going with "hot as shit" for a thousand alex:thumbsup:
Just a wild guess here, but have you looked at the roots?
Those plants look unable to sustain themselves.
They raid the leaf stores, then die when it's gone.
That means they can not feed, or their sap is gettin' sucked before it heads north.
Prime suspect is Root Aphids!
Pray that is not the case, but pop one out of the pot for a post-mortem exam and take a look.

If not, good!
But, what shape are the root in?

Roots tell the story. Their like a report card. (8 inch pots)
Bro, you have Multiple issues going on! Heat being the number 1 culprit. Doubt its a lighting issue cuz they appear to be flowering ok. Dutch is possibly correct but again, methinks its heat! IMHO. Need to get that exhaust fan spinning for the next grow cuz I think its toast?

I'll have to agree with the heat issue, I know its a hard one to control. Maybe get a couple of extra exhaust fans or a cooler of some kind. The symptoms also can indicate root problems, such as root aphids, or worse, root rot, a fungas that attacks the roots. To check for that gently remove the root mass from the pot ( easiest when soil is dry) and check the color of the roots. Are they a nice white color? Or are they brownish or tan looking?
If dealing with a root problem then a hyrogen peroxide flush will help. I use a 28% hydrogen peroxide that I got at the hydro store and use 5 ml. per gal of water and give it a good flushing. This will kill virtually everything in the soil, and supplies extra oxygen to the root zone. I've had plants come back from the dead doing this.
You have to get a handle on that heat issue though first thing. I had to purchas a small portable swamp cooler to cool my flower room down as I couldn't go with a air conditioner due to not having sufficiant electrical supply, which would have been better.
Check the roots and let us know.
Hope this helps
plants are dying for our negligency. For this we are suffering. We should plant mor trees.
