Brewersfriend allows you to select from pellet, leaf/whole, plug and fresh/wet.
For first year hops, assuming they have been dried, smell great & hoppy (vs. plant/green/chlorophyll-y) when you crush a few between your hands, and have lots of sticky yellow lupulin, I would suggest using the BF default amount for Cascade/leaf less 30%. After Year 2, reduce it by 15%. This adjustment info is from a presentation I watched from either Hop Union or Fresh Hops several years back and was tailored for homebrewers.
I've been brewing with homegrown hops for more than a decade. FWIW, once a plant reaches its 3rd harvest I start calculating recipes at the low/mid point of their IBU range. As far as I can tell, I've never substantially over- or under-hopped a beer using this method, so I stick with it. I've used BF for the last three years and have found their default AA% to work pretty well for homegrown hops of many varieties.
Congrats on getting some usable cones in Year 1. Feed them with some well composted manure from your local farmer or bagged manure from Lowes/HD, then stand back and be amazed next year. You aint seen nothing yet!
