I doubt very much that a couple of handfuls of dynamic lifter in a 50lt bin would burn your hops. Dynamic lifter is pretty much just chicken poop as far as I'm aware, which has been processed into pellets.
More than likely your hops are suffering nutrient deficiency like a lot of people on here.

Thanks Bob, I think I'll stick to Maxicrop fortnightly until season's end. Looking forward to seeing how good of a harvest your Chinook produces. If it's anything like your Mother in law's tomatoes, you should have cones the size of pine cones!
