Hi! Newbee question again here! Why my leaf have those spot and drying? Wind burn? Cold night? ( they are outside ) can I trim it? Those are auto flower about a month old . And why the leaf are pointing down? Have this problem after 2 day of big wind and 2 cold night. ( not cold enough to freeze but not that far...)

Calcium deficiency
 
I give them guano last week ( half the recomended dose)
The affected growth won't recover. Just keep an eye on the new growth. Bat guano typically has plenty of calcium so the issue is likely resolved. Like I said, just monitor the new growth for any symptoms.
 
Almost looks more like nutrient splash around the bottom leaves or they made extended contact with the soil or side of the pot.
Guano can be quite hot especially if it gets on the leaves.
If it were wind or cold it would have affected more than just bottom leaves I would suspect.
And If that's coco then it looks too dry

pretty sure its not splash I use a Baster for watering my plante and its soil not coco. But i like your theory meaby with the wind the leaf touched the soil
