Your pics are so blurry as to be useless, but that combination of overfert stress, HIGH humidity, high temps, and fan crapping out, sounds like you may have got yourself a case of the ROT. If so, that plant is toast. Sorry. Keep your %RH around 50 and your temps in the 70s.
stinkyattic Reviewed by stinkyattic on . I NEED HELP NOW! PLANT DID A COMPLETE 180 IN LESS THAN 12 HRS!!! If anyone can help me I need it fast. I have no idea what drove my plant to this state, but it happened yesterday in less than a 12 hr period. I checked on my plants at about 11:30am and came home about 9:30pm and it went from 100% healthy looking to shriveled and limp. I have been giving it 12/12 light with 2 CFL lights in the red spectrum and one in the blue (all running at 43 watts a piece). I've had the plant on the 12/12 for about 2 weeks and been giving it a 5-30-10 miracle grow plant Rating: 5
