I suspect the improvement is due to high humidity.
Or more explicitely water available at roots. This Phrag does great with wet feet. So dry vs wet could be a huge difference.
As far as low/high K and longifolium comparisons, I have a big longifolium in a 8or 10 inch pot for several years.
Always thought it was doing good up until going low K. Leaves got 20% longer and don't see burned leaf tips any more. Leaves also darker, and firmer substance. I haven't seen any significant change in blooming characteristics (which I always thought was fine to start with).
On the other hand the plant is definitely not dying of K deficiency.
Yet another unscientific anecdote.
