Help Particle size over lifetime

[Barbelot]

Hello,

I am trying to create a constant stream with Obi Fluid with a source that emit constantly.
However I run into an issue where the particle removed as they reach their lifetime limit create visible blinking as they disappear instantly.

Here is a gif of the issue : https://imgur.com/Pzgkvnh

Is there a way to make the particles fade out in size or color as they reach their death ? Like a size over lifetime or color over lifetime parameter ?

Have a nice day !
