Even though one Amnesia seems to be held back i'm not gonna give up on it :) I am sure it will catch up to the rest of plants considering it was last one to sprout so it's few days behind rest. Gonna keep on caring for it and see where it will lead. Even if it's gonna yield few grams it will be still nice learning experience!
So far all plants seems to be happy and growing perfectly fine, let's hope it won't change throughout upcoming weeks :D
