What granular feeder should I give my autoflower at D35?

I will tell you what I am doing with my powdered formulas if you like but it's better for a pm conversation... I am using a 0-54-30 and a 0-0-64 but with some serious thought going into how it's being used so we'd need to kind of discuss as there would be "timeframe" but a growth frame of when and what to add.. The bulkers only really start to help in 3rd to 4th week of flower but also the plants need lots of light to use up the higher feedings..
