I went to your thread to look at your set up, but don't want to wade through all of it, tonight.
Sorry to hear of your troubles.
A sexed plant with at least six leaf pairs, a foot tall is worth $25 where I live.
Hell, newly sprouted seedlings in peat pots bring $5+.
A plant two feet tall and sexed will bring $100 in May.
Regarding "hardening off" a description of your lights, etc. would help.
"Sunburn" occurs when a plant is started in weak lighting conditions and then moved into strong sunlight.
I move my plants into a greenhouse very young(read back in this thread). The light is bright in the greenhouse, and acts as a mid step in the hardening off process.
Put your babies under a tree where they'll get direct sunlight early and late and shaded from about 9AM to 4PM. Or get a greenhouse.
I hope things are going better for you.(And quit doing shit that gets you in trouble! Being a Grandfather forces me to say that shit.)
