Different seeds in a pack aren't clones.
Of course there are different strains.
Of course if the environment is different it will effect the plant and it's potential.
Most of what you've said has little or nothing to do with clones.
I'll stand by what I said.
"if you were correct then there would be no reason to look for phenol type"
"and I never said you were wrong"
That is exactly what you did say and that is wrong. The question is about clones, no where does the OP ask about anything else. So all the verbiage about selection and strains is irrelevant.
How long you've been cloning is also irrelevant, of course.
