Bubba Kush / Exodus cheese / Jack Herer

can see plants really bushing out and yellowish/light green cola sites since changing to 12/12 about a week ago (07/07/20 todays date). Started with bio bloom and top max on last watering, started with 2.5ml of each may give extra 0.5ml of each next time and see how they take it. Also does anyone have an opinion on bio heaven and when to use it too? i have an old bottle of it but didnt feel like it done anything on my last grow but may have been using it wrong so just ended up sticking with the grow, bloom and top max trio.
