Speaking in general, genetic mutations are "mistakes" that occur in replication.
So if a plant is "replicating" or growing and an error occurs in this process, you will potentially have a mutation. (As all genetic defects in replication don't necessarily produce a phenotypic alteration/mutation)
In theory, further growth from the mutation will perpetuate the defect.
I think because superthrive/homornes stimulate faster growth, there is a higher likelihood of a replication mistake. Think of cancer...a fast growing collection of mutated cells. All cancer comes from normal cells that created a "mistake" when replicating. It seems logical that superthrive can and does cause mutations.
Furthermore, I would think the new growth producing the mutation will perpetuate the defect. However, I have no experience in this and would defer to experimental studies if they exist.
Another question is whether the old growth can be effected with the mutation. I would think NOT....but I don't know for sure. Again, experimentation would yield an answer.
My question finally is this: If the new growth has the mutation, and the old growth does not, then will removing the new growth (and of course removing the hormone ie. no more superthive) restore the normal blooms?
I will try to find some information on this and if anyone already knows the answer then please enlighten

Quite a fascinating topic imo
