Weird pheno or symptoms?

hot soil, low humidity, high temps, plus i think distance ( or power output) is too big, plant very stretched. in most cases when root system gets a bit bigger, all sorts out, but you have to make sure, that above mentioned things are in right . I nursed way sader plants, even autos . good luck !

Under most circumstances, leaf curling in cannabis plants points to an excess of some sort in the plant's environment. More specifically, the root cause (no pun intended) is either an excess of temperature or humidity. Sometimes overfeeding can also be the cause. My recommendation would be to maintain a grow environment that does not exceed 80 degrees Fahrenheit. And keep an eye on your humidity levels, because anything over ~70% could also be the cause of your troubles. Good luck with your grow!

Yep, weird beginnings, but it will probably grow out of it.
