I would say around 5 degrees. If you are around 25°C during lights on optimal temp. for lights off would be between around 20.
Cold nights can bring out the purple and red colours if you are searching for a colourful crop.
Check out my Diaries i had two crops of Dos Si Dos 33 (the same genetic), one of them turned out dark purple due to a lower night temp. Roo cold nights will affect yields for sure!

Sorry hat the question earlier before but I'm new here so I dont know how to undo the solved quesion status. The LED has about 300W and I want to dimm it. not simply turn it on/off. Preferably with some kind of integration in home automation systems like Home Assistant. Thanks :)

When did the flowering start?The LED panel, after switching (Ts600 Mars Hydro), stayed slightly on even during the dark hours. I managed to fix the issue, but I'm not sure how to count the flowering period. The plant had shown some differentiation, a few pistils, and a bit of stretching. What do you think?

Too much light or PH imbalance?I dont know, something strange about the color, the spots on the leaves maybe? suggestions accepted. Maybe I need to add a fan ASAP, or let more air into the tent?
Dimmer is sset to 20% 25% , maybe I should give more light? or maybe less?
