She's been a problem child from the get go. First her helmet stuck to her head and I had to use a fingernail to slide it off, after waiting 36 hours. Then when I added the 2 AutoCobs, (1 for her and one for sissy in 32x32in shower), her leaves curled up and I raised the cob over her from 18 in to 24, (and then she stretched like no plant ever has). It's been over a week when I first noticed the discoloration. First it was just a different shade of green.
