Hi there I do it similar to
@growinggrannie, but I use veg nutes until about week 4 or 5, depending on how the preflower/early flowering looks then I switch to bloom nutes. I do think the way growinggrannie runs there's helps the autos hit the earlier harvest window where as my way seems to take a bit longer to get to harvest. Feel free to look through my recent/current soil grows as I have been quite detailed in what I do for a change.
