Late airlock action

[Brewharhar]

3 days ago I added a few hop pellets to the end of the secondary fermentation of a Pilsner, at the time there was about 1 small bloop in the airlock every minute, and it had been in secondary fermentation for exactly 2 weeks.

Now it's blooping rapidly as if it has returned to full fermentation, there are a few bubbles around the edge.

Is this normal? And should I wait longer now until I bottle. Hoping I have not ruined the beer and that it's not the hops rotting or similar.

If anybody else sees this, this is why.

When hops are added at this stage at or near end of secondary fermentation need to allow another week or two for the beer to clear. Sometimes the beer will foam for a while. It is not fermenting. it's just acting as a 'nucleation' point for dissolved CO2 in the beer, will see blooper going off, may briefly need blow off hose.
