Help with Roots Original/Uprising feed schedule!

Struggling to find any advice on a feeding schedule for Roots Original Soil along with their uprising lineup. Currently running autoflowers on day 19/20 that look great but dont want to be too late to top dress. Has anyone used either the soil or their Uprising lineup that could offer some advice?
Thanks!

Also if growing 2+ weeks in original soil, you can start feeding, 3-4 weeks for finicky strains.
