Help me save my girl!

Question from a fellow grower:

I have a plant about four feet tall and very close to flowering however this morning I checked on it and the leaves were wilted and crisp. Still a dark green but the ends of the leaves were black. It was wilted last night when I came home so I heavily watered it. Can you help me save it. It has turned cold in my garage and I have had a little heater in there along with a pan of water. Help if you can.

Too much water will drown plant. First leaves will get dark green, then splotchy, then curl n die.

Such short change makes me think it’s nutes or PH issue…but…too much water and cold can damage as well.
