my question is... does the overall condition of a marijuana plant effect the genetic values passed down from a mother plant, into a seed/seedling?

lets say i treat a marijuana plant couple(male & female alike), given that they are... lets say northern lights... with bare minimal basic needs in order to mature into fertilization.

i know this is an exaggeration, but if its true with extreme conditions like this, it holds evidence towards optimal growth conditions having an effect towards genes passed in a positive way. will the seeds that are produced mature into the same strain of northern lights? or will it be under par in terms of next generation?

thats a tough question, and i dont have experience with it, i am a biochemistry major and am looking for personal/anecdotal experience that will help me understand.
