I agree 100% she looks over-watered but that is where I am stumped. She only had one soaking watering, making sure prior to that she was dry using the finger method, and she instantly drooped. But even if I concede that that first watering to run-off and the flushing I did afterwards(post-drooping) over-watered her, drying her out doesn't seem to be correcting the problem. Prior to the pictures above I had her sitting for at least a week on top of the catch pan inverted with a fan blowing directly on the pot. I then kept lifting the pot until it was totally light. So light it scared me that I added 1 liter of water just in case while I try and search for a solution. I have 3 other plants, different strains, that I watered exactly the same and none of them behaved like this one. I am getting a moisture probe in the mail today to use as a double check, but I think I've got a good feel now for the pot weight.
As for heat stress I can't be certain because I am not 100% knowledgeable regarding what it would take to heat stress them. But I highly doubt it because I am in the Northeast US in my basement(where it is in the low 50s) and I need to keep the lights on 24/0 just to keep the tent at 70-75 degrees and it never once reached 80 degrees.
I do appreciate all the responses and help, thank you. I can't express how frustrated I am with this, none of the straight forward stuff I am finding on the internet seems to be leading me to a solution.
