HydroOrganics Earth Juice Grow Germination, 1-Quart

What amount should i put on my plants? Should i mix it with water or directly? At what stage should i start using it?

Has anyone used this in their aquaponic systems. Is it ok for the fish? Or would you use it as a root drench. Or spray it on the plants.

is this just for hydroponic and can it be used outdoors for cannabis?

How thick is the solution? I want to inject this into my drip irrigation system (fertigation) but don't want to risk clogging the emitters. Thanks!
