Royal kush auto in the cantine boyz

Hello guyz here we are week 4, i move the plant in a bigger growbox but the room where i put it its colder so im struggling with the temperature, i have a mars hydro fc e3000 with a 100x100x180 growbox, if someone have the same lamp and can suggest some light % is more than welcome! With this problem i ended up burning a little bit the leaf tip but nothing too serious and thats it for week 4. like always if you have any tip just comment below😎 byee guyz see ya the next week
