Well actually Thalia can probably do all that stuff you mentioned, but so far all we've seen from Jason is lightning, so your assuming he has electricity powers on par with his sister. And with the poison thing, its now canon-ish Percy can take water out of liquids and use it, so bloodbending(or at least plant-draining) is a possibility, either of which he could use pretty much everywhere.

Now the above statement is one I would not like to happen, but I'm just showing that we can't just put add-ons on their powers.
