Can a worm casting ratio of 1-0-0 give enough nutrition to auto cannibis plant

The pot is a 2 gallon

The only answer I can give you is "maybe". So, a fertilizer that is a 1-0-0 is at a low concentration so anything below 0.5% on the macronutrients doesn't have to be labeled. It's more complicated on the micronutrients, but regardless, there isn't enough information. So, the most I can say is maybe. You'll have higher nitrogen than anything else, but that's all I can say.

I'd say probably not. I haven't grown.autos though yet (not till it warms up a bit anyway) but I would think the ewc is not enough by itself. It depends on what you mix it with though too. For instance if you mixed 20 pounds of ewc into an already mixed soil like green fields or ffof then it might get you through decently. As far as a.medium like pro mix or sunshine I'd probably have to say its doubtful.
