The dosage recommended by the company is as follows.
Dosage BioGrow Vegetative growth: 12 - 18g/Gal substrate
Your using 11L or 2.91Gal, so 12g-18g x 2.91gal = 34.92g/11L - 52.38g/11L
Your using just under half the dose amount for the suggested ratios from the manufacture. Might be a bit to little.
I have used stuff like this before in soil grows. Gaia Green, is dry amendments from whole sources like bone meals and such. It does take time to break down and the finer the powder the fast it is available to the plant, surface area increases the rate of decomposition. Typically dry amendments are top dressed every 3-4 weeks. 8 weeks is a bit much. I'm sure their is still some left in it but the majority is all done and gone.
I would highly suggest using their bio enhancer or some other form of microbs to help break it down it also provides micros to the medium via sea kelp A++.

their feeding guide is a bit weird. but looks like you add things in at the start and then follow though with the bloom formula around week 4 or 5. But this will all depend on when your flipping to flower. I still would do a top dressing every 4 weeks. even half the recommended ammount if you plan to flip to flower soon.
This also have a nice how to for fertilizing with these amendments.

I like how they break apart the bloom feeding in two parts for the flowering period. I would stick to what they are suggesting in bloom and see how it works. Looks like they know what they are taking about.
