My experiments with KelpMax overdosing are consistent with this. Given an overdose of the KelpMax growth stimulant plant growth that would otherwise not happen was overwhelmingly obvious, but that growth seemed to hit hard limits.
For example with very old back-bulbs (e.g. 8-10 year old C. violacea bulbs), KelpMax sometimes failed to produce results no matter how heavily I dosed the division. With other very old back-blubs heavy dosing eventually forced new growth and new roots, but the new growths matured with the size of recently deflasked seedlings.
Another example is overdosing healthy growing plants. The KelpMax overdose almost always caused single lead plants to grow multiple new leads with amazing root growth, but again, there were limits. The new growths were mature and had sheathes, but were invariably somewhat stunted in size.
Again, for the record, I don't advocate giving overdoses of KelpMax, which is now sold as KelpPak I believe. What I described above was an experiment intended to prove (to me) that KelpMax was capable of causing growth that would would not otherwise occur. By overdosing I was able to get growth that was obviously abnormal, but the outcomes achieved by overdosing were not necessarily desirable (e.g. I would rather my backbulbs put out one larger growth rather than two very small ones, and that I didn't get so much roots growth that top growth came out stunted).
