Amnesia auto second grow

Well things seemed to be off to a good start. Then she just kinda stalled out. Not really sure why either. My uncles plant is right next to mine, they have both been getting fed from the same mixed nute watering can. Both have the same environment parameters. I guess the only real difference besides genetics is the fact that I planted right in my final pot.. whereas my uncle used a solo cup. Could that be what's going on? If so, then why did it work the first time with amazing results!? Haha.. anyways, I'm sure we will get this resolved soon. If not. I may do another Durban poison run. February 27th update. Replanted in a peat cup with pro mix soil. Plain water. Whether or not this decides to take off I have started two Durban poison beans. March 1st update: see last picture
