It's not really a new feeding schedule but I used something close to it last grow with auto flowers. I just used the 4-4-4 at the 1/4 cup rate mixed in at planting and then top dressed at the onset of flower with more 4-4-4 and switched to flower girl 2 weeks later. I top dressed every two weeks with flower girl at the 1/4 cup rate after that until harvest. I also used Epson salt and molasses throughout. I'm doing 2 tbls per gallon of 4-4-4 this grow at planting and will top dress again at flip with the 4-4-4 then switch to flower girl. I'm new to dry amendments but this did a good job for me. Adding EWC this time to try and get some more compost into the mix.
