Leaves drooping after transplant please help

Hi all

I've got a plant that I had growing outside for 5 months and now since the winter came in I've had to bring her in. Night temps dropping to 3 degrees celcius. She was in a container outside which is almost the same size as the one she's in now. When transplanting, we had to shake a bit of the soil off the roots to make it fit but the root ball is still intact.

The first three days after transplant were fine, the plant went on as normal, then I saw the lower leaves all started drooping and now on day 5 all the leaves from bottom to top are droopy. I watered once on day 2 and haven't again since. The soil meter shows that the top of the soil is almost dry and deeper down its wet.

I moved it under a 600w hps inside, Ive since turned the ballast down to 250w as someone told me the sudden increase in light is not good.

The plant is in week 5 of flower and I need to save it, please help. Here are some pics

It's always bad to transplant a flowering plant, it stresses them out. Especially if you have to fuck with the roots. The stress can cause it to hermie (bananas). Reducing the light intensity was a good move. If the humidity is low try to bring it up to 50%. If it recovers then it recovers. It would be okay to water it, over watering is a constant thing so watering a little soon one time isn't gonna hurt, in this case it will help.

Thanks for the help. I misted the plant every few hours and she started bouncing back.
