Low water column nutrients = massive root growth?

I kept getting green dust algae in a buce tank, so I decided to basically remove all Nitrate and Phosphates from my dosing.
Only dosing potassium and traces.

What I found really interesting is 1 week later all my buces started sprouting new roots. Keep in mind I've had them for months at this point with nearly no root growth.

When plants aren't getting all the nutrients they need from the water they can grow more roots to get it from the substrate instead. Either that’s what happening or else it just recently got used to your tank and started growing.

The difference is quite shocking here. I've had the buces for months and they've grown new leaves during that time. Very little root growth.
But after a few days every single buce either has grown new roots, or has shoots sprouting that will become new roots.

This is actually extremely useful information for buces.
if you're planning to plant them into the substrate, it helps them access more nutrients/ammonia from the soil.
If you want them to attach themselves onto rocks, root growth helps with that too.
