heat stress advice pls

All you can do is wait, and continue to provide for her. Make sure it didn't dry out as well.

@Sciolistic_Steve Or getting so high you fall asleep on water day and everything wilts...

well, point the heat elsewhere? i'm assuming you didn't know the heater was stuck in that direction until the 'hours later' point. anything that can still be supplied by working veins can recooperate. give it a sec. it'll shed the dead ones. if any bits are necrotic, you can cut that off if you want. you'll know more tomorrow. if auto, definitely goingn to impact yield and if photoperiod you can just vege extra as needed to regain anything lost at cost of time/electricty. shit happens... leave a timer off or set wrong etc.. lol.. turn off the exhuast to apply a foliar spray then neve rturn it back on till 24h later... it happens. my favorit - fall aslepp while filling reservoir... that was fun.

Don't panic! I can't see your plant's situation but you described it fairly well. You gotta keep on top of shit dude. Heater fan direction included. Make sure your shit functions correctly. Make sure you service your gear and take care of it. Anyways, ya you probably fucked up a few leaves, but don't worry Weed is pretty tough. If it's got nutrients at the right pH, light, some water, and a little breeze, it'll bounce back. Don't pick off the damaged leaves just leave them for now. You've freaked the plant out enough. No need to cause further stress right now by snipping off plant material. I know you're freaking out, but if you haven't boiled the plant, it will recover. Don't dump a bunch of water in the roots and don't mist it. There's nothing you can do. The damage has been done. I guess if you had some B1 around you could give it some B1 which helps with plant stress recovery. Just wait it out, and don't fuck up like that again son!
