Rusty and culring leaves

Don't seems go better, maybe she is too young for that light, I'll wait crossing my fingers.

I am a new grower, but tend to err on the side of caution, so as far as watering put your finger about an inch or knuckle deep and if it’s dry water, if wet you’re good. But here’s a link to check https://www.growweedeasy.com/cannabis-plant-problems/overwatering Def looks like some over watering. Maybe something else but as said I’m not sure Good Luck :)
