What strain is s/he

Hello,

I have 3 auto flowers going and 2 randoms (the random seeds you get from Nirvana when you purchase anything) and this is my first grow - She's almost a month into her veg cycle and I can't figure out what kind of strain s/he is going to be.

Is it to early to tell? And at how young can you determine male or female? Should I be able to figure it out now?

need better close up photo, use macro if you have it.

The easiest way to tell is the leaves. If the fingers of the leaves touch and the palm, then it is an Indica. If the fingers at the palm do not touch, it is a Sativa. It doesn't get any easier than that. Keep in mind, most strains are a hybrid to some degree and can exhibit both pheno types.

I grew out 4 of those nirvana mystery seeds last year and I kid you not they were all the same strain, it kinda pissed me off as I love nirvana strains and have grown them for years. Every single one was a sativa dominant hybrid they all grew kinda tall and lanky way taller than the widows I bought with them they yielded pretty low like an ounce from a 3 foot plant that was topped twice, they all looked pretty similar but the thing that for sure convinced me they were all related was when you rubbed the stems or flowers with your finger they all had the exact same smell not sweet or skunky at all but just like the smell of mushrooms but a little intensified. It was the strangest smell I've ever smelled from weed ever and I hated it!!! Worst taste ever, and they all wanted to go like 11 or 12+ weeks and I'm use to 8 weeks strains
