I agree that most characteristics will be maintained, except, your plant might possibly be more prone to some things... IME, powdery mildew. Reveg on 2 strains has made clones from the mother show powdery mildew in flower when I had never seen PM on the clones from the mother pre-reveg. Jmo, and could have just been with my genetics, not others. Genetics were SPG leaning S Tooth and Joey Weed Apollo 11 (which is already known for PM).
Potency and smell was unchanged,,, growth characteristics like branching however were changed. Jme.
We might be talking about two different things... I'm speaking on revegging a plant to become a mother then give clones... sounds like previous posters and OP are referring to regrowing a single plant, to be flowered again. not exactly apples to apples.
