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

The leaves are wierd shaped, but growing fast
Hi everyone! Please tell me, is it a consequence of leaf scorch with light, or incorrect watering, or I was very in vain in the beginning added root booster? The big question is, is it worth waiting for a potential recovery?There's nothing like it at google

What can be the causing of the leaf curl upwards beside the obvious? like heatstress, waterdrops or maybe roots? seems also unlikely to me she has the same feedings as the strawberry. my other plants are fine. more info in the text. Thanks in advance

Everything seems to be OK except one thing (week 3). I thought using the greenhouses at night made this, but it doesn't. When I check the plants early in the morning, their leaves are slightly curled upwards, just along the edges. As the hours go by the leaves flatten. Any clue?

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.

Curling leaves - heat stress?
Some of the leaves are curling. Sits next to another indica that doesn’t seem to be affected. Temps here in Arizona have been 100-110 for weeks. I presume this is heat stress but would 💗 2nd opinion. She’s in the most protected area of the garden, so probably can’t fix this.

Help with burned leaf tips
The tips of some of the leaves have begun to dry, curl, and look to be dying (see pics). I think it's some sort of nutrient burn, but I'm unsure. I water every other day w/ a solution of Miracle-Gro 24-8-16 at 50% recommended concentration. Used distilled H2O last 2 waterings.
