Black Widow / Blue Dream Monster Crop

Oof was a great week till Wednesday night. No clue what happened to my timers but they left the lights on for an extra 6 hours. Unfortunately this caused the tent to heat up quite a bit. In the tent it hit 90, the solution of the buckets hit 83. Blue Dream 1 and 2 had little to no effect along with Black widow 1. Black widow 2 on the other hand suffered. Which is upsetting because this one was doing the best and performance had suprised me the most. She shot up so much she towers about 8 inches over the other plants. The only thing I can think of and have had a few other people agree is that the bucket solution got too hot, decreasing the dissolved oxygen in the water, presenting symptoms like "overwatering". So it didn't get enough oxygen and is now drowning. This morning I had noticed she is doing slightly better. I've verified all timers are working appropriately and have also opened up side vents on the tents so we can get some colder air from my lung room in there. I also added another air pump and two air stones to try and get as much oxygen into the roots as possible. Covered any holes with duct tape to keep light out. I also added some yoyo's to help support the top bud sights that are now very limp. I hope it doesn't die =( We've had some crazy weather here in Michigan over the past few days, 30 degree swings is making it hard to regulate the temperature. Has anyone had any similar experiences and what did you do to remedy them? Any feedback or help would be greatly appreciated.
