Heat Stress

So my girls are outside on my balcony and about 2 weeks ago we had some upper 80's and 90 degree weather. 1 of my girls, the smallest ones got put in a heat coma and wilted crisped up and basically died. The other small one's leaves curled up but haven't wilted so I am not sure if she is too stunted to be brought back to life..
Question is I am heading to work in about hour and a half and it may get to 80 degrees today.. They were watered 2 days ago and I am wondering if I should bring em in the house for the day?

seems weird that they cant handle 80-90 degrees, they should handle that no prob. obviously 90 is hot, but it shouldn't kill it! I mean, my plant hits 90 occasionally, and it does fine, it just doesn't really grow in that heat, but it don't die! I wonder if something else is going on.

or, maybe the suns 90 degrees is hotter then my lights 90 degrees, I really don't know for sure...I thought a degree was a degree. lol

I second that.
My plants took 110 degrees last week that made them lose some leaves. They r all reveg again and growing "ok". They certainly didn't die!

any temperature in typical environment should be survivable for the plant. it's weed after all. the reason must be something else, possibly triggered by heat. I doubt that it was heat only, that killed your plant.

At 80 degrees I would try partial shade that way the plant
can get that umph from the bit of sun.

Maybe there in a sort of heat trap on your balcony..they need a nice cool breeze as well...to much heat and stress and the plant will close the stomata on the leafs...your pot could be to small aswell..

I thought the same thing. My thoughts were how does the plant sustain life in its natural habitat when there is no human intervention. My pH is within specs, I am not over or under watering. Only 2 out of half dozen were affected with one completely shriveling up and turning dark brown and crisped right up within a day or 2. Just worried cuz of work today so I can't assess them till tomorrow morning when the sun comes back up.. I decided to bring em all in the house near the window with the door open and screen closed with fan blowing lightly on em.. I do have to say the 2 that were affected were the weakest and smallest of the bunch..

They get direct sunlight from sunrise till about noon and it's usually breezy being on an upper level floor. Here is a pic of the survivor.

Looks like nitrogen toxicity

Ya know you could be on to something.. I'm using nutrient preloaded soil mix of Vermofore and fox farm ocean Forrest and I was told for about a month just give the girls straight water which I did for a month up until that feeding.. So shoul I just use plain water till it perks up?

You should "flush" with pure water.

I always use liquid neuts just a few days after I transplant with FFOF with never a prob.
I can't say it would work for you but I bet it would.
To be on the safe side I would let the soil dry out then just use plain water for the
next few waterings. Your plants look like they will turn out fine.

He said a month because its slow release nutes added...its hard to flush because of that...iv seen growers go start to finish in ff only adding teas to it with good results

I was given some Tea as a recommendation from a hydro store so I added some to the water this morning.

How old or your plants and how long or they getting that heat outside ..just feed with plain water your probley givin it to much to soon..

try keeping the plants out of direct sunlight for a fw hours during the hottest part ofthe day ..they look a bit drained..

Mostly clones with one mystery seed (which has been the strongest so far). Had them since roughly the middle of April in 5 gallon pots. They see the sun directly from around 6am to noon so they don't get direct sunlight during the hottest part of the day. Not to mention it doesn't get crazy hot where I am at..
