I see we can make our own custom buffs.   Is it possible to make it so if we have symbiotic relationship out on the tank and they dont have lifebloom on them a buff comes up?   Maybe this is asking for too much   Its just I dont really understand the @#> syntax   

This can only be done when the two buffs are non-secret, and unfortunatelly "symbiotic relationship" buff is secret.

For another two non-secret buffs, yes its possible display a square or shape indicator, when a buff is up and another buff is missing.

 I must be blind because on first inspect i did not notice symbiotic relationship is not secret. So this is possible, for example to display this info in a square indicator (a colored square that shows up when some status is active):

1. Create a square indicator to display the information (Indicators > Right panel to create new indicators).

2. Create a "symbiotic relationship" statuses>buff in buffs section.

3. Create a  "lifebloom" buff  in statuses>buffs section, set a full transparent color to this lifebloom buff.

4. Link the "simbiotic relation ship" and "lifebloom" buff to the square indicator,  lifebloom buff should be the first in the statuses list of the indicator. 

With this this setup the indicator will display a square with the "symbiotic relationship" status color when this buff is on, but the square will become transparent/non-visible if Lifebloom buff is already applied.
