Maybe I should have added more detail to that as I didn't mean to offend.
In a good soil grow there is probably lots of all needed nutrients so adding bloom foods may not show that much of a difference unless there are deficiencies. I mostly grow either DWC or in soiless using hydro nutes and that is really dependent on timing and inputs as they are all the plants have to grow with.
Doing side by side grows with identical plants from the same mother showed some decent increases with early application of bloom food. Mainly just some extra Bloom and a half dose of Big Bud a week before flipping compared to starting that at the end of week 2. Checking my daily ppm drop in DWC showed up to 4X the feeding rate during the stretch then a rapid drop back to late veg rates. I'm pretty sure it's the same with other grow methods but harder to measure.
