It looks like you are having some issues with temps and humidity, maybe compensating with spraying more often, usually with high temps leaves will curl upwards. But if given to much water and roots stay soaked it will sometimes droop and curl downward. Try keeping a consistent temp and humidity. Itโs okay to fluctuate some but itโs the 10,20+ degree and humidity that I find I have these same issues. In some pics I see the plant is very healthy looking and then some where it isnโt. If you have been giving it nutes then it probably isnโt lacking..so to speak but just isnโt able to uptake the available nutes because sheโs stressed.
