Also if we could would the bottle “Flower” be considered the “Bloom”? In ANs Grow, Micro, Bloom?
Yes and no … if your going to use your own nutrients then you shouldn’t fill the bottles… you should be mixing your own nutes and the filling the grobo
I mix my own …
Yes what @chris_barfield said because if you fill up the bottles more than likely you are going to seriously damage your plant
Not to mention the damage to the 
machine!
Danger, Danger, Will Robinson! 
U ever figured this one out? Would make Sense they trying to keep it a secret to keep us buying from them but honestly 50$ each grow Defeats the purpose of this box

You need calmag, micro nutrients, macro nutrients, pH Up & pH Down. You can use the bottles above to store them in your Grobo.
Why wouldn’t we just refill the old bottles ?
Hey @David_Flores,
Don’t want to use Grobo nutes? I’d unplug all the bottles and run a nute regiment by hand dosing your reservoir. You will need a pH and EC meter do have success doing so. Kinda defeats the whole purpose of using an automated system though.
You will kill your plant if you pour different nutes into the Grobo bottles, even if you match them correctly. Your recipes won’t match the dosing schedule we’ve created.
Cheers,
Stephen
To avoid reactions. Someone on here added another brand of pH Down to an empty Grobo bottle and the bottle ended up melting.
