Didn't come back and still not telling anyone he fed it 8.0 ec calmag, leading them in circles.
Folks are guessing heat, venting, CO2 poisoning, bugs, lights, transplant shock or some mystery blight.
From elsewhere on the web from his 5 threads :
"The leaves are crispy and dry and smell like dried cannabis when I open the tent. I wonder if it's possible these symptoms might be from heat stress or possibly a combination of that and gnats."
He's fed it a crapload, raised the lights and left the tent door open so the bugs will leave maybe, problem solved.
