That's great! Take care not to put too much, as you dunno the proportion of NPK on each, it could lead to over fertilizer on Nitrogen or any other.
Humus normally has 1-1-1. Bat guano depends a lot on what these bats eats! And the sea thing, if it's from fish, is something around 5-2-2.
If the price is ok, and you have a lot of plants, these are great products, but i would use them with small amount.
