Just givin a plant in flowering stage need advice on what to do asap?

Hello everyone im in need of some help, i was just given this plant and for a couple of days it was in a room that was too hot and wasnt getting the right cycle of light. some of my leafs are really dried out and not so sure if its going to live. This is also my first plant so im hoping for the best! :/ lol...Also this was grown outdoors and is now indoors for what i believe to be the flowering stage is going from outdoor to indoor not good? As i said before i was given this plant out of nowhere so i didnt have the right set up, currentley its in my closet which is equipped with a thermometer and humidity device fans and a fluorescent light, im curious to as if this light will work and any other advice would be great. Just ask if you want to see more pics, Thanks everyone

Why don't you just throw it back outside if you're not prepared?

no where safe round here plus i dont want to move it all around again its already been through enough stree i believe, it started on my buddys patio and he moved so im keeping it in side...anything i should do theres brown spots appearing on my top leafs and littler spots on the stem?
