You can use them as suppliments, but you're going to need more.
Neither have much Nitrogen in it, and you need nitrogen for plant growth. (first number is the amount of nitrogen - the bonemeal is 1-15-0, the fish mix is 2-0.2-6.6). So you are alright for phospate and potassium, and probably trace elements, but need a fertilizer with some nitrogen to begin with.
Something like a fert rated at 15-3-3 or similar, and then switch to those ferts you already have come flowering and budding time (as you wouldn't want to use a high nitrogen fert at flowering time, the nitrogen is just for green growth time and slows flowering anyway)
