Looks like it has a little heat stress, but still very healthy looking for being in high heat all week.

Yes light heat stress but nothing to worry about. Mother nature has always taken care of herself outside.

Curled leaves
Why my plant's leaves curl up like that? I think that there's an overwatering issue, but is there any way that my soil is not good?

Why are leaves curled?
Im a little bit freaking out about those curled leaves, don't want to fuck up Another grow. I figured out on my own that i have small magnesium defficency added 0.1ml/l calmag. The smallest plant literally break leaves because of curling, how can I save this one?

Why are some leaves curling strangely?
Hello everyone, the problems begin unfortunately. Why are some leaves curling strangely? I have not given any nourishment, the temperature and humidity are constant, will it be a problem of PH or EC? Thank you in advance.

Cupping
On the right plant in diary pic it shows slight upward cupping on the edges of a few leaves. There are a couple of others on the other side. But 95% of the leaves are fine. During my first try at LST I broke the main stem by 70%. I think this caused the cupping?

I hate Canoeing
Leaves are "canoeing" alot. I can't do anything about the "heat" because it's outside. The plant looks very healthy otherwise, I just wish it didn't have that symptom.

WHAT IS CAUSING MY LEAVES TO CURL? (Day 64 pictures)
The leaves at the top of the plant seem to be curling up. My first guess is that there is too much light. I recently moved my light down to 12 inches above the canopy. The PPFD should still be under 1,000, but I don't know what else could be causing it. Please help. 🙏

Flush?
I have never tied to flush a plant and I seen if the leaves have too much yellow then it is not a good idea. I plan on doing a harvest in 10-14 days and wanted to know if both of my plants should be ok with a flush.

Classic N toxicity (:
Heyho :) since she has progressing leaf tip burn and curled tips which I'd almost certainly say is a nitrogen toxicity, would you recommend going down to 50% general strength or maybe leave out the grow supplement at all and just feed Bloom? Cheers guys :)

First time growing/Need help in late flower
Over the last 9 days my plant has gone from happy and healthy to sugar leaves pointing straight up near the top of plant and drying and curling up on the lower levels. Is this from too much light or did I over feed late in flower? First grow/ no diary. Can I save or do I chop?

Leave curl weird shape
Yeah this plant curled the first 3 set of leaf but others plants in the same condition don't do that. I wondered if it somekind of genetic issue or it's just normal ?
