Not sure whats wrong with this guy. Hasn't grown or stretch an inch for the last couple of weeks. I don't think it will get much bigger. It has been topper twice and had some mites and over heating issues so not the easiest of lives, but in comparison to 2 others in the same tent, it's pretty stunted.
Will persevere and see how he finishes up.
Onwards and upwards
doesn't loo dead... keep it up and off wet soil and see what happens. don't know what options you have. another seed or cutting / room for 3 if it does survive etc... just cover your bases for the area you need to fill so as not to waste electricity=money or time/effort.
