I love the bone meal blood meal question...I have grown with these you mix them together with a couple tblspoons crushed(very important) dolomitic lime and perlite...

But...!st you have to have sterile soil or some with the least amount of ferts you can get...

So, for a 20 lb bag throw in a cup of each in a big tub with the soil and add 40 % perlite...10% peat and get it nice and wet. Check PH level after a day...you do this by taking a sample of run-off water in the tub...

You DO NOT Fert again unless you notice a deficiency9and then you try to address that particular problem, until you are ready for flower.

Before you induce flower/change photoperiod...you mix another batch and repot 1-2 weeks before...

In between you water with ph'd water...

Bone Meal and Blood Meal will work for you, BUT, But, ... These ferts will Fry your babies if you OVER DO IT!!! I know...there, I admit it...lol
