Honestly im not very aware of any type of use for the bone meal as i havent used it...as long as your not experiencing any negative effects like burn, drooping, yellowing etc. then i would say your doing just fine.
On the other hand lets start with the vegetative period of growth: this is when your plants are striving for nitrogen.
Fertilizer Ratio: N-P-K, Nitrogen-Phosphorus-Potassium. Vegetation needs higher N (ie. 4-1-2) Flowering need higher P-K (ie. 1-5-7) you really want K to be higher. =)
On the contrary, you are a beginner. So the best thing right now is to use a one part veg nutrient (which means a single bottle nutrient).
I would recommend dynagro as a #1 beginner nutrient as its a one part veg and one part bloom. very easy and there are a lot of alternatives which you can just ask a worker at your local hydro store about.
Good Luck My underdog.
