Help my plants seem to be dying!!

So i'm at just over 9weeks into flower, all was going ok but now the leaves seem to be dying. i have three plants and the leaves on all three are drooping. All the leaves of one have turned yellow and seem to be dying. i haven't changed anything except i haven't been giving nutrients with every water. please take a look at the pics attached and let me know what you think. Help what do i do?

Not a pro, but I'm pretty sure what you are experiencing is normal if you are 9 weeks into flowering, the plant basically kills itself off. Also when you flush and drop the nutes during the last couple weeks or so it deprives the plant of nutrient uptake.

Are the leaves crispy and.brittle? The appear to be twisted and curled if they are also crispy and.crumble when you touch them it could be mold/but rot.....if they were just yellow id agree with the gent above, that's meant to happen in the last few weeks when flushing, cannot comment on the drooping though. Could be over/under watering, heat stress, ph, could be a number of things

It seems to me that they were way under watered and are also experiencing heat stress, jmo.

those arent pics of a healthy plant at the end of life, it has been stressed and the crispy leaves are the sign something is wrong.

thanx for all the input guys. what do i do now? the leaves are not that crispy and brittle and they are still very much attached. i tried to remove some but they're not coming off easy. check out how they looked a few weeks ago

tall thin and wispy and stretched, but look healthy!!!

Yeah, that's not the natural fade at the end that happens to some strains. When the natural fade happens, the leaf itself retains its full structure, it just fades from green to orange/purple/yellow. That's totally different from curling, twisting and drying out, which is what you have.

When I had something similar happen, it was heat stress. Temps just too high. I ran AC into my tent to cool it down and the plant did fine. The crisped leaves eventually fell off, and I cut off everything that was more than 50% damaged.

Good luck! You still have a ways to go in flowering, so I hope you figure it out.

Sorry, but it looks like your plants suffered heat stress.... The day they did, maybe a day 2-3 weeks ago, when it got above 88 f in your grow space. The plants that had less water on/in them when heat went off kilter, are the ones that look worse... The roots quit taking up nutes... it looks like PH lock out, but I'll bet you heat stressed them.... So what happened 2 -2 1/2 weeks ago ?

And if it is heat stress they are done, it will only get worse... plants quit up take of water? Pots heavy?
