Heat stress, nitrogen toxicity or underwatering???

We had a upper 90's degree day yesterday and my back deck plants had to be watered twice. Im using FF nutes and I gave 1.5 tbs of growbig, 1.5 of tiger and 2 of big bloom for the first watering and when that dried out I watered with molasses as usual. It was only a half tbs more of growbig than I have normally been feeding her since I've been trying to keep my leaves greener going into flowering I thought I would give a little more nitrogen and now I see something fucky on my GSC plant this morning. . It's sister, 9 lb hammer, took it lovely however and had exploding new bud growth and no bad leaf symptoms. That's why I think I might have fucked her up by letting her dry too much, because this morning around 4 AM when I left, they were still kind of heavy and didn;t need watered, but I didn't check again until noon or so, and they were pretty light and I noticed this. She has just started flowering in the last few days while the 9 lb hammer which has been for a week didn't have any ill effects. Will this effect yield since Im going into flowering as long as the leaves stay green and not crispy??

I know when my tomatoes dealt with heat I just used plain water back in to re hydrate.

Maybe it'll cool down and they'll recover a bit.

I dont think so man I went out there and they look way worse. It just baffles me how they took it so bad but the other strain is just fine

Will a plant that looks like that be able to produce quality bud? I know the yield will definately be drastically reduced, but it should still be able to produce dense bud right? If its gonna be a bunch of popcorn, Im not wasting any more nutes on it

id say there both over watered and too hot. the leaves are curling away from the sun which shows you there hot. and im sure if you watered them twice in 1 day they must be over watered. what size pots are they in and how much water do you give them?

Cant be overwatering man it's 3 gallon pots and in 90 plus degree days during rapid growth the pots dry out multiple times per day. I was going to transplant into 5's so I didnt have to water so much but I was afraid of stressing them out during the transplant. I use the pot lift technique so I am very in tune witrh how much water the plants are using and when they need it.

Take a pic in the morning. Outdoor plants give false reads at end of day, dropping leaf position and curving if temps dropped a lot. If that leaf tip claw is still there in the morning, you over fed.

Does the sun hit those black pots ???

The roots are getting too hot!

Put the pot in something white or better yet - dig a hole and put them in! Reduce the pot/root temp!

Be careful about watering......A little "lack of water droop" is better then any over-watering!
Too wet too long screws with the pH and nutrient availability...

Good idea buddy, you are right those pots sit on my deck and they do get pretty warm. Next year I think I'm gonna put some of my reflective grow room material around the pots

Ive noticed mine do this when its hot and my plants are very thirsty to the point where they are starting to droop a bit and then I give them a good watering. Within a few days they return to normal.
