big buddha cheese x blueberry

so my mate brought me a Big Buddha Cheese x Blueberry germinated seed round lastnite, he got them fro barneys farm, has any1 grown his that could give me any info?? I just harvested a lemon strain which I also have 2 clones of, it was a very nice smoke. only got about an oz off her and would love to up that with the blue cheese! also I know this sounds thick but I was given some nutes (in rong container) and I not a clue wat it is and the friend can't remember pmsl! it must be coca of some kind coz the smell is bit like chocolate lol, is this any good to use on my babies??
the little seed is now about an inch above soil and the case is dropping off, can't wait hehe!

+rep for info

Never use any nutes that you dont know what it contains, easy way to kill your plant. Also im sure you know this but dont give a seedling any nutes for a few weeks.
