Plant vigour

It's ages since I last posted on this forum, in the main this is due to my tanks running soundly with no issues. Excepting the major lighting issue with my Trigon 350 that is.

My question is does a plants strength decrease over time. The plants in my smaller tank have been in there for a year now, constantly pruned, replanted etc. The excess growth has fully stocked my Trigon.

I am happy with my fertiliser and CO2 regime but some of the stem plants do look thinner and less vigorous than they were. Does the hi-tech forcing of growth reduce their long term vigour? With terrestrial plants you do have to re-stock periodically, is this the point I'm at?
