I have just recently flipped my OG kush to flower , and i got some bud blood made by advanced. I am aware of the dosage but am not familiar with the length or extent of how long into the flowering phase I can use the power bud blood.
Use it for the first week of flowering. You should see the sex within a week. I used bud blood a week before 12/12 through the first week of flowering. I saw pistils within 3-4 days. For the second week on you should use a bloom booster like big bud.
