Oh yeah, Nukeheads IMO are the worst, I've seen it personally, I've not grown any personally, but a workers brother (Plow) put all his eggs in their basket 2 years ago for his outdoor run, and got burned. Nothing was as stated, not even close to the same genetics, I mean it's one thing to have a couple different phenos, but not like Plow had, most never reached the 2ft mark, and then he had some that grew 8-10ft but were lanky, node spacing was huge, and buds didn't even hit "golf ball" size and yielded practically nothing to talk about with an 8-10ft'er.
I really hope that the mother Lemon Cane you kept tests well, hopefully that will help you recoup some of your money spent on the nasty run of their genetics.
Hell, I think I've got some "Funeral Cake" seeds left that I'd send you so you could give them a try, they hit the mark for me last year, real nice frosty tasty smoke, the hash I made from her is real nice, a peach/mango taste mixed with a peaches and cream taste from the pheno I had.
