Не известное зерно

I don't think anyone will be able to tell you what strain or variety this is. If it was bag seed from some other plant, then its part that plant, but what it was crossed with is unknown, Maybe it was its self, maybe it was a different plant in tent or different plant from outside. You could maybe say its a bit more Indica leaning hybrid as its leaves look a bit more fat and squat then long and skinny like some sativas, The one main problem with this logic is that plants are crossed so many times between each other it does not really hold true anymore. If anyone says they know what it is, they are full of shit. You and you alone have the best information on what it is based on the fact you planted it and sourced the seeds from somewhere. Good Luck!

The autumn colours are typically from cold temps at night or genetics at end of life, natural fade is one way they describe it. The yellowing could be from lack of N if its on the lower older growth, not typical to see it on upper growth if lower growth exists. Your almost at harvest only a few weeks to go, i would not worry about this, your plants are looking good. Good Luck!
